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...

Which of the following is NOT a rule for constructing a simple frequency distribution? Question 1 options: The number of class intervals should equal the number of observations measured. Each interval is equidistant. No overlapping class intervals are allowed. Values are rounded to the same degree of accuracy measured in the original data.
