What is the name of your database?
2. Choose and write down the name of any quantitative and continuous variable from your database 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)
