Homework Answers
If the shape of a distribution is unimodal (having one mode) ,Left skewed ,no outliers present :
better measure of the center for this distribution would be the median Because many values may fall far away from the average value(Mean)

Unit 6 Lesson 3 Classwork (Adapted from Math Vision Project) Data Distribution A lot of information can be obtained from looking at data plots and their distributions. It is important when describing data that we use context to communicate the shape, center, and spread. Shape and spread: Modes: uniform (evenly spread- no obvious mode), unimodal (one main peak), bimodal (two main peaks), or multimodal (multiple locations where the data is relatively higher than others). Skewed distribution: when most data is...
