The first and third quartiles are descriptive statistics that are measurements of position in a data set.Ã Similar to how the median denotes the midway point of a data set, the first quartile marks the quarter or 25% point.Ã Approximately 25% of the data values are less than or equal to the first quartile.Ã The third quartile is similar, but for the upper 25% of data values.Ã We will look into these ideas in more detail in what follows. The Median There are several ways to measure the center of a set of data. The mean, median, mode and midrange all have their advantages and limitations in expressing the middle of the data. Of all of these ways to find the average, the median is the most resistant to outliers. It marks the middle of the data in the sense that half of the data is less than the median. The First Quartile ThereÃ¢â¬â¢s no reason we have to stop at finding just the middle. What if we decided to continue this process? We could calculate the median of the bottom half of our data. One half of 50% is 25%. Thus half of half, or one quarter, of the data would be below this. Since we are dealing with a quarter of the original set, this median of the bottom half of the data is called the first quartile, and is denoted by Q1. The Third Quartile There is no reason why we looked at the bottom half of the data. Instead, we could have looked at the top half and performed the same steps as above. The median of this half, which we will denote by Q3 also splits the data set into quarters. However, this number denotes the top one quarter of the data. Thus three quarters of the data is below our number Q3. This is why we call Q3 the third quartile. An Example To make this all clear, letÃ¢â¬â¢s look at an example. It may be helpful to first review how to calculate the median of some data. Start with the following data set: 1, 2, 2, 3, 4, 6, 6, 7, 7, 7, 8, 11, 12, 15, 15, 15, 17, 17, 18, 20 There are a total of twenty data points in the set. We begin by finding the median. Since there is an even number of data values, the median is the mean of the tenth and eleventh values. In other words, the median is: (7 8)/2 7.5. Now look at the bottom half of the data. The median of this half is found between the fifth and sixth values of: 1, 2, 2, 3, 4, 6, 6, 7, 7, 7 Thus the first quartile is found to equal Q1 (4 6)/2 5 To find the third quartile, look at the top half of the original data set. We need to find the median of: 8, 11, 12, 15, 15, 15, 17, 17, 18, 20 Here the median is (15 15)/2 15. Thus the third quartile Q3 15. Interquartile Range and Five Number Summary Quartiles help to give us a fuller picture of our data set as a whole. The first and third quartiles give us information about the internal structure of our data. The middle half of the data falls between the first and third quartiles, and is centered about the median. The difference between the first and third quartiles, called the interquartile range, shows how the data is arranged about the median. A small interquartile range indicates data that is clumped about the median. A larger interquartile range shows that the data is more spread out. A more detailed picture of the data can be obtained by knowing the highest value, called the maximum value, and the lowest value, called the minimum value. The minimum, first quartile, median, third quartile and maximum are a set of five values called the five number summary. An effective way to display these five numbers is called a boxplot or box and whisker graph.

Makayla Logan Mrs.Loving English III 12 November 2014 Teenage drug abuse is an issue that can result from a wide variety of social influences, stressful events, and mental disorders. Drug abuse among adolescents is a troubling issue because it decreases focus, increases the chance of consistency in behavior during adulthood, increases the chances of developing emotional issues, permanently damages the brain, and damages tissues in every system that can lead to death. Previous scientific research has identified that social factors, including the media and peers, play an important role in psychological development and impact the adolescent s decision to start experimenting with substances (Edwards). Appropriate solutions for the teenageÃ¢â¬ ¦show more contentÃ¢â¬ ¦Teens usually abuse certain drugs that people usually wouldn t think they used . The most popular drug that teen abuse is tobacco products, cannabinoids also known as marijuana, cold medications, inhalants such as gasoline or ammonia, depressants, stimulant, N arcotics like morphine, oxycodone,codeine, hallucinogens, Dissociative, or Club drugs like ecstasy know as X (Edwards). At least 3,900 children under the age of eighteen have either tried or have been offered one of these drugs (Ã¢â¬Å"FactsÃ¢â¬ ).

High expectations; harmful or helpful? Many parents want their child to be top of their class, make straight AÃ¢â¬â¢s, and be something to brag about at the parent teacher conferences. Having high expectations for your children helps their mind set, education, and end results. Some people think it overworks the kid or lowers their self-esteem, although it has been proven that children who were expected to reach their parents expectations, do. We will write a custom essay sample on High Expectations. or any similar topic only for you Order Now First of all, having high expectations for your kid at early age will help the child over time. They will grow up learning that they need to excel so they will not just one day, give up. Parents who set expectations usually see their children rise to their level of expectation. So setting the standards at high but achievable levels will cause children to step up even further making it easier in the long run. Some people do believe having these Ã¢â¬Å"goalsÃ¢â¬ , for your child can lower their self-esteem, but how could someoneÃ¢â¬â¢s self-esteem be low when they are successful and making profitable living just from the expectations that were set for them as a child? Parents who expect their child to make amazing grades, talk about school, and check up on their childÃ¢â¬â¢s progress in school regularly helps the child but if a parent neglects this weekÃ¢â¬â¢s quiz in, letÃ¢â¬â¢s say math, they send the wrong message to their children. Helping them study for the math quiz is an important part of setting the expectation for college. For instance, many families in Asian countries have set the expectation for their child early on so they grow up thinking that if they donÃ¢â¬â¢t excel in school they are a disappointment. Therefore, these children overachieve in all that they do. They do great in school, go to college, and make a fairly nice living. This race has been known to be very smart and prosperous. So, wouldnÃ¢â¬â¢t it be great if everyone became successful from high expectations and a little push from the parent? Finally, the end results. Being a child with parents having high expectations is a gift. If the parent pushes them to reach their expectation thatÃ¢â¬â¢s just helping the child be successful in life. Those parents just want them to live a happy-fat-wallet-life. People say it may over work the child but really that child is working towards success. A little hard work isnÃ¢â¬â¢t hurting anybody if they know the outcome. Say a child made outstanding grades all through school due to the parents pushing them to. Then, they went to college, letÃ¢â¬â¢s say Harvard; why? Because the kid grew up thinking he needed to excel. Well, that kid goes to Harvard, learns valuable skills, works hard for a high paying job, then ends up living an affluent life, successful and happy all because you had the right motivation. All in all, look where their parents pushed the kid to. They could of said, Ã¢â¬Å"Just try your best. Ã¢â¬ but no, they said, Ã¢â¬Å" YouÃ¢â¬â¢re going to DO your best and your going to get there. Ã¢â¬ High expectations help you have the motivation to reach what is expected of you. Why are you expected to be your best? Because you will definitely not get there by just being Ã¢â¬Å"alright.

Money may be able to buy ones happiness but not necessarily satisfaction in life.

One can have satisfying materials, do satisfying things, and obtain satisfying qualities. Characters in Ã¢â¬Å"Winter DreamsÃ¢â¬ and Three of the most satisfying materials that a person could own is a home, money, and a car. At least one of these items is essential for a person no matter where they live. The home is the most satisfying material that a person could own. A home is a place that one can go to rest, eat, and just live. A home provides memories and a place for a family to grow. A home satisfies people with protection, an investment, security, safety, and privacy. The home is definitely a key item of satisfying materials. Another satisfying material that a person could own is money. Money is something that is very important to possess. Owning money can satisfy a personÃ¢â¬â¢s hunger, shelter, and just everything it takes for that person to live. A person would not be satisfied if they did not own any money.

3 Types of Parenthetical Problems 3 Types of Parenthetical Problems 3 Types of Parenthetical Problems By Mark Nichol 1. The survey found increasing demand for customer experiences that are difficult, if not impossible to deliver with legacy systems. Writers sometimes carelessly neglect to close a syntactical door after opening it. In this case, Ã¢â¬Å"if not impossibleÃ¢â¬ is a parenthetical interjected into the main clause, so a comma must follow as well as precede it: Ã¢â¬Å"The survey found increasing demand for customer experiences that are difficult, if not impossible, to deliver with legacy systems.Ã¢â¬ 2. Similar to the Internet in the 1990s that transformed business models to adopt e-commerce and new ways of working, cryptocurrencies and blockchain have the potential to disrupt in ways not even imagined. There is only one Internet, but this sentence implies that more than one exists, and that the one in question transformed business models in the manner described, but the reference to transformation is parenthetical, and nonessential to the main clause, so it should be set off with a comma as a parenthetical by preceding which, which replaces that to signal the nonrestrictive nature of the parenthetical: Ã¢â¬Å"Similar to the Internet in the 1990s, which transformed business models to adopt e-commerce and new ways of working, cryptocurrencies and blockchain have the potential to disrupt in ways not even imagined.Ã¢â¬ (The comma that separates the subordinate clause, Ã¢â¬Å"Similar . . . working,Ã¢â¬ from the main clause, Ã¢â¬Å"cryptocurrencies . . . imagined,Ã¢â¬ doubles as the parenthesis-closing punctuation mark.) 3. Three board members, John Doe, former CEO of World Wide Wickets; Jane Smith, CEO of Global Tetrahedron; and James Jones, executive director of the Church of the SubGenius; voted against the measure. The series of names and job titles is parenthetical to the main clause, Ã¢â¬Å"Three board members voted against the measure.Ã¢â¬ However, the punctuation marks that open and close the parenthetical do not match, and all the semicolons are problematic because they syntactically cut off Ã¢â¬Å"voted against the measureÃ¢â¬ from the rest of the sentence. The simple solution is to replace the overkill semicolons with commas because the sentence structure precludes confusion about the corresponding names and titles: Ã¢â¬Å"Three board members, John Doe, former CEO of World Wide Wickets, Jane Smith, CEO of Global Tetrahedron, and James Jones, executive director of the Church of the SubGenius, voted against the measure.Ã¢â¬ Alternatively, if the writer insists on using semicolons, splice the two parts of the main clause into one uninterrupted statement as a setup to a list that follows a colon: Ã¢â¬Å"Three board members voted against the measure: John Doe, former CEO of World Wide Wickets; Jane Smith, CEO of Global Tetrahedron; and James Jones, executive director of the Church of the SubGenius.Ã¢â¬ Want to improve your English in five minutes a day?

Contemporary Issues in Economics - Research Paper Example Therefore, this paper will seek to explicate some of the main factors that determine the gas prices, problems, causes and solutions. First and foremost, it is important to note that the supply and demand market place determines the worth of fuel. This is because an increase in demand and a decline in supply will automatically lead to a rise in price. On the contrary, if the demand goes down or there is an upsurge supply, then the fuel price will automatically decrease. In case a retailer decides to market its gas at a high price without considering the pricing of the competitors, then consumers will go and buy gas from the competitor selling at lower prices. When this happens, the retailer will lose business due to the high pricing and this will compel him to lower his gas prices in order to be competitive and maintain his customers (Ã¢â¬Å"What Affects Fuel PricingÃ¢â¬ ). Retailer competition also affects gas prices and this can be grasped by the differences in price on stretches of highways that have multiple gas retailers. When there are several choices that consumers can choose from; then it boils down to more competition on the retailersÃ¢â¬â¢. In as much as many retailers carry gas and oil from major oil corporations, they are independent merchants of the product. This implies that they have the freedom to set the prices the way they so wish. Chevron Corporation asserts that, crude oil is merchandized on the global market just like agricultural products such as corn and wheat, and precious metals such as silver and gold. In recent times, the prices of crude oil have increased dramatically as a result of the rising world demand and political instability in most of the oil producing countries (Ã¢â¬Å"What Affects Fuel PricingÃ¢â¬ ). Crude oil is the most important raw material used in gasoline and other petroleum products production. Therefore, it plays an integral in determining the price of gasoline. Crude oil price may be up to half the cost of one
