The mean (or sum of data entries divided by number of entries) of 2270, is only very slightly larger than the median (the data at the middle of the sample), and the mode (the data entry that occurs with the greatest frequency) which are both the same at 2207. This represents a very slight affect by the outliers at the high and low ends of the data sample, indicating that the mean presents the most accurate description of the data set. (Larson & Farber, 2011. pgs. 66, 67, 68). [See Exhibit A].…
The definition of the ‘mean’, is an array of numbers added together and then divided by the amount of those numbers. The reason the first definition is incorrect is because it isn’t the maximum value of figures, it’s the total amount added together.…

How could graphics and/or statistics be used to misrepresent data? Where have you seen this done? Statistics, graphics, and database are used in medical field to approve, prove, or disapprove theories, analysis, and interpretation of ailments, medication and it’s impact, and treatment and it’s effectiveness. However, these data can be easily misinterpreted when and where there is a vested interest. Individual opinions are generalized without considering whole aspects of the issue, thus forming a biased opinion.…

This report is based upon the book “Damned Lies and Statistics: Untangling Numbers from the Media, Politicians, and Activists”, written by Joel Best and published by University of California Press in 2001. Joel Best, a professor of sociology and criminal justice at the University of Delaware, has written a highly readable treatise on statistics, and how we can become better consumers of the statistical information that permeates the environment in which we live. Joel Best is a sociologist and, as a result, this is not a book about the mathematics of statistics, but about its sociology. That is, a book about the ways in which bad statistics are generated and spread through society.…
“Excerpt from Damned Lies and Statistics: Untangling Numbers from Media, Politicians, and Activists” by Joel Best described how numbers and statistics can be used to skew the view and opinion of the public. Using numbers that aren’t always actually false, statistical analysis can be used to support either sides of an argument. I found it interesting how you can find two numbers that have wildly different outcomes even when the numbers are technically correct. On top of this American as a whole is a large, sometimes ignorant, consumer of knowledge; believing any number they see on a news outlet or from a reputable source.…
Comparing Mary Meeker’s 2016 numbers to earlier year’s data from Statistica, we know people are installing more apps (37 vs. 27 apps), spending more time in apps (4-5 vs. 2.8 hours) and using more apps on a daily basis (12 vs. 4-6 apps).…
A common misconception is that statistics provide a measure of proof that something is true. Instead, statistics provide a measure of the probability of observing a certain result. It is easy to misuse the statistics in data analysis even to the point of misconception because statistics do not introduce systematic error which can be introduced into the data intentionally or accidentally. There are many associated variables in statistical numbers that the person analyzing the data does not see, and without further explanation or supportive data, one can easily come to the wrong conclusion and the scientist data could be presented as facts rather than probability. If the source from which the data was gathered was not factual, then this will reflect a statistic that is misleading, biased, and based on false information, but those persons who might later interpret the data had no idea that the source was not factual, and as a result wrong information is publicized. Because statistics deal with numbers they often seem to be more convincing and less suspicious of false claim than descriptive arguments, but numbers can be easily manipulated in favor of someone’s opinion.…
Statistics can be used in many different ways to deliberately mislead the audience. One major way is by adding a break in a graph as seen above. Another way to deliberately mislead the audience is to change the scale of the graph which makes it looks like it went up or down more or less than it really did. Also, another way the audience can be deliberately fooled is by using a bad sample of data. If you ask people questions and you know they will all say the same thing then you may just ask that group of people the question but you can say it came from a study of the whole population. This leads people to think that more people than actually do in the general population believe/ agree with the question you are asking them. Another way statistics can be misleading is if you ask a bias leading question. This would be a question were you are suggesting the answer before the respondent has a chance to answer the question. "If you say don't you think" before the question this would be a bias leading question. Also, you can skew what the average of something actually is by using the arithmetic mean, mode and average which are all technically the average. Lastly, you can use volume instead of bars to make it look like there was a huge increase or decrease in something when there really wasn't.…
Statistics show eighty-five percent of youth in prison, seventy-one percent of high school dropouts, ninety percent of homeless and runaway children have an absent father. Fatherless children and youth exhibit higher levels of: depression and suicide, delinquency and teen pregnancy, behavioral problems, illicit and licit substance abuse, diminished self-concepts, and are more likely to be victims of exploitation and abuse (Kruk 49). I believe both parents should be equally responsible in raising a child, physically and emotionally. Both parents should help each other raising a child to set an example of how a family should look like instead of putting everything on just one of them. If both parents work as a team in up-bringing a child it enriches the child's life, giving him or her much more stimulus along with enhancing self-confidence and influences their personality. Ultimately both parents influence the future life of a child and how he or she will perceive the world, along with their levels of happiness, morality and productiveness, and their academic successfulness.…

For over two thousand years Jezebel has been known as the bad girl of the bible, the wickedest of all the women. The ancient queen has been denounced as a prophet of false and foreign gods, a witch, prostitute, killer of innocents, and enemy of the one true God. Before her time as queen of Israel, she was raised as a princess in the kingdom of Phoenicia where she grew up as a priestess of Baal, there most powerful god. The story of Baal is a god that dies in spring, and a goddess of love and war mourns. But after an endless summer with drought and famine Baal is resurrected in the fall bringing with him rain and storm. Baal because of his time of resurrection was the god of fall and autumn, rain and therefore the god of melancholia and sorrow. He was the god of storm, the maker of thunder and lightning bolts, and the god of fertility and sex. He was also known as Prince Baal or the rider of the clouds and in the bible he is often called Baalzebub, changed to Beelzebub in the New Testament. He brings with him several goddesses such as Ashera, The Queen of the Sky and Astarte, the lunar goddess symbolized as a star within a circle (often seen in witchcraft today). She also was a goddess of fertility sex, and war, this was not only a sexualized religion, but a violent one to. Slashing and cutting oneself was a part of the religious ceremonies, as was human sacrifices, sometimes even child sacrifices. Jezebels life was formed around such beliefs, and from the day she was born until her death she stayed faithful to her gods. Her background shows that this is all she knew, and in her land to worship these gods was normal.…
How often do people lie? If someone asked you how many times a day you lie, what would you say? People most commonly say they lie two times a day, this is an understatement. In actuality people lie about seven to eight times a day. Men and women tell different kinds of lies. Men tell self oriented lies, which means they tell lies about themselves. Women tell un-oriented lies, which means they tell lies about other people, specifically lies about other women. Typically, women are better liars than men. People who are good at lying are usually caretakers, teachers, people who deal with children, people in the arts, high self monitors, people in control of their nonverbal behaviors, and people who want to learn about nonverbal behaviors. Women are most possessive of these qualities which…
With a mean you would be looking to find the average value, which is simply the sum of all the values divided by the total number of values. For example you have 12 test scores that the total sum is 998, you would divide that by your total number of value (12) you get 83.17 average test scores this is your mean. The median, or middle value, is the center of an ordered list of numbers. So you would have half of the values on one side and half on the other. The median is the middle value. When using the mean as a measurement, extreme values can have a major effect on the mean outcome, in which case researchers are likely to median…
