What can cause the mean to be misleading?

• A small sample size

• A large number of data points

• A symmetrical distribution of data

What is a bimodal distribution?

• Data without a mode

• Data with two modes

• Data with one mode

• Data with more than two modes

How can the relationship between mean, median, and mode indicate data distribution?

• All three always indicate a uniform distribution

• If the median is the highest, the data lacks outliers

• If all three are the same, the data is normally distributed

• If the mean is higher than the median and mode, the data is skewed left
