How can you describe a distribution?

• A distribution can be described by its shape, center, and spread.

• A distribution can be described by its maximum, minimum, and range.

• A distribution can be described by its mean, median, and mode.

• A distribution can be described by its variance, standard deviation, and interquartile range.

What is the purpose of comparing distributions?

• To identify outliers in the data.

• To understand similarities and differences between sets of data.

• To determine the mean and median of the data.

• To calculate the standard deviation of the data.
