# Statistics Homework Help

**Question description**

During this unit, you will investigate different
numerical measures for describing data, and you will also prepare for
the cumulative MSL Midterm Exam. The exam includes concepts covered in
Chapters 1–4.

You will use Excel in this Discussion. Excel graphs and charts do not
paste into the Discussion Board. Therefore, please place your entire
main post, all parts, all graphs, and all portions into a single Word
Document. Then, use Add/Remove to upload and attach that document to the
Discussion Board as your main post.

Data Set: Garbage.xlsx

1. What is the name of your dataset?

2. Choose and write down the name of any
quantitative and continuous variable from your dataset and use Excel to
calculate the mean, median, mode, min, max, range, variance, and
standard deviation for that variable. Paste the results into your main
post (or use Add/Remove to attach them).

a. Which measure of center (mean, median, or mode) does the best job in describing your variable and why?

b. Which measure of center (mean, median, or mode) does the worst job in describing your variable and why?

c. Include
(type in) the value 50000 into your selected variable data. Now,
recalculate the mean, median, and the variance for your variable (now
that it includes the extra value of 50000). How did this change the
mean, median, and variance from their original values? Is the change
what you expected? 3. Choose any two quantitative variables
from your dataset. Use three numerical measures to compare these two
variables. Next, create a bar graph that includes the mean and median
for both variables (to visualize their comparison).
