Applied Statistics Quiz

6. Analyze results - Graph the data from Table 4 and describe what your graph looks like (you do not have to submit a picture of the actual graph!).

1. For the following scores, find the mean, median, and the mode. Which would be the most appropriate measure for this data set?

Due to financial hardship, the Nyke shoe company feels they only need to make one size of shoes, regardless of gender or height. They have collected data on gender, shoe size, and height and have asked you to tell them if they can change their business model to include only one size of shoes – regardless of height or gender of the wearer. In no more 5-10 pages (including figures), explain your recommendations, using statistical evidence to support your findings. The data found are below:

4. Calculate the following measures of central tendency for the set of cube measurement data. Show your work or explain your procedure for each.

4. Give the mean for the median column of the Worksheet. Is this estimate centered about the parameter of interest (the parameter of interest is the answer for the mean in question 2)

11. For each of the following, indicate whether you would use a pie, line, or bar chart, and why.

• Provide at least two examples or problem situations in which statistics was used or could be used.

5. Give the standard deviation for the mean and median column. Compare these and be sure to identify which has the least variability?

6. The most appropriate graph for this data set would be a line graph because it showcases trends and findings within the trends.

Descriptive statistics are digits that are used to summarize and describe a given range of data (Klenke, 2008). Basic descriptive data includes, mean, median, mode, variance and standard deviation. The data can be rearranged in an ascending order as follows:

What I gathered from the thoughts and facts of the 2014-2015 AP Statistics students, were explicit insights on how rigorous and demanding the class is going to expect from me. I understand my math background has not placed me at the best starting point for AP Statistics, but I also know that statistics is not like algebra. In Algebra I would spend hours after school trying to understand the material, only to receive little to no progress on the days a test. I recognize that in Statistics we will be given homework every day, but will not have it collected or graded all of the time, and acknowledge that it will take discipline, maturity, as well as self motivation to not fall behind and get it accomplished because in the end it could either set

A pharmaceutical company is testing the effectiveness of a new drug for lowering cholesterol. As part of this trial, they wish to determine whether there is a difference between the effectiveness for women and for men. Using   = .05, what is the value the test statistic?

The box plot of the appendix of 11, 12 and 13 represents the results on lower (bottom) and higher (top) quartile. The band located inside the box and is always the second quartile (the median). Moreover, the box plot has two lines where are extending vertically on the top and on the bottom of the box (whiskers). The top of the upper and lower whiskers shows the upper and lower extreme.
