This document discusses various statistical methods for analyzing paint data from two brands, including calculating the mean, median, mode, variance, and standard deviation using both the table method and shortcut method. It also discusses how the mean, median and mode differ for symmetric versus skewed distributions.

1. Finding the median

2. Calculating mean and finding mode(s)

3. The paint data

4. Calculating means and ranges of paint data

5. Using the table method to calculate the variance of Brand A

6. Likewise for Brand B

7. Using the shortcut method to calculate standard deviation

8. Mean, median & mode of symmetric and skewed distributions
