Exploratory Data Analysis

Exploratory Data Analysis Using the dataset Chamorro-Premuzic. sav, exploratory statistical analysis was carried out on the variables in the dataset. Scatter plots were formulated t give a clear visual view of the data for Extroversion and Agreeableness. Descriptive statistics were also formulated for the variables. 2. Decision about the missing data 3. Correlation A correlation analysis was carried out on the data for Extroversion and Agreeableness.

Describe The Error In The Conclusion

Describe the error in the conclusion. Given: There is a linear correlation between the number of cigarettes smoked and the pulse rate. As the number of cigarettes increases the pulse rate increases. Conclusion: Cigarettes cause the pulse rate to increase The intention of a LINEAR CORRELATION ANALYSIS is to resolve whether there is a relationship between two sets of variables. We may find that: 1) there is a positive correlation, 2) there is a negative correlation, or 3) there is no correlation. We cannot deduce causation from correlation: correlation does not imply causation. The main problem with all correlations is that there are many models consistent with any correlation: the correlation between two variables may be caused by a third,…

lies,damned lies and statistics

“Lies, damned lies, and statistics” is a phrase describing the persuasive power of numbers, particularly the use of statistics to bolster weak arguments. It is also sometimes colloquially used to doubt statistics used to prove an opponent’s point. The term was popularised in the United States by Mark Twain (among others), who attributed it to the 19th-century British Prime Minister Benjamin Disraeli (1804–1881): “There are three kinds of lies: lies, damned lies, and statistics.” This Line stresses on the fact that common errors, both intentional and unintentional, associated with the interpretation of statistics, and how these errors can lead to inaccurate conclusions. It is a phrase attributed to the power associated with figures. The phrase is commonly used to doubt…

The benefit of homework

This article was written by Dorothy Suskind, a 1-st grade teacher in Richmond, and an adjunct instructor for the University of Virginia and the University of Richmond. In it she did research that consistently showed that homework has only a slight effect on student’s educational achievement. She expressed that it was a brave act for her to challenge the practice of giving homework and its benefits. If correct, she knew she had to answer questions like, “What will the parents say? How will children learn self-discipline and study skills? And,” How will my child prepare himself for tomorrow’s work force? She knew that she and other researchers had to be advocates for the children they taught and speak out at…
