1. Write a statistical question you could ask your classmates about the movies they like.

2. Line plot Tally chart

3. Statistical questions can be divided into two groups: categorical or numerical.

4. Categorical data is measured qualitatively by placing the items into categories or groups. Ex. Favorite color, male or female, hair color Categorical data is often displayed using a bar graph or a circle graph

5. Often times, categorical data does not involve numbers, therefore will not have a mean, median, or range. The mode is the answer that occurs most often. The mode is the most useful calculation for categorical data.

6. Numerical data is measured quantitatively and has a value or number for which operations such as addition or averaging make sense. Numerical data can be analyzed to find mean, median, range, and other forms of measurement Numerical data is often displayed using a line plot (dot plot), histogram, or box and whisker plot. *We will study each of these in more detail throughout this unit
