Longer on the right side of its peak than on its left

A pattern where individuals within a population are spaced out evenly across a given area

A data set with two distinct modes, or peaks, that can be used to study ecology and other fields

Multimodal distributions

Probability distributions with more than one mode or local peak

Used to visualize data distributions (also called the structure of data)

The average of how far each value is from the mean

The square root of the variance

Standard deviation corrected for sample size

How related two variables are to each other

Shows relationship between a numeric and a categoric variable
