Question

1. match the experimental questions below to the appropriate graph from model 3. a. “is the number of candies in a bag of chocolates dependent on the color of the candy?” graph _ b. “does the length of a person’s leg affect the time it takes them to sprint 60 yards?” graph _ 13. why was the data for graph d plotted in a bar graph?

Explanation:

12a. The number of candies is a discrete quantity that can be counted. A bar - graph is suitable for comparing discrete data. So, a bar - graph would be appropriate as it can show the number of candies for each color category clearly.
12b. The relationship between leg length and sprint time is a comparison of two variables. A scatter - plot is ideal for showing the relationship or correlation between two numerical variables. So, a scatter - plot would be appropriate to see if there is any pattern between leg length and sprint time.

1. Bar graphs are used to display categorical data with their corresponding frequencies or amounts. If the data for Graph D represents categorical data (such as different categories of items and their counts or amounts), it is appropriate to plot it in a bar graph.

Answer:

12a. Bar - graph
12b. Scatter - plot

1. If the data is categorical, it is appropriate because bar graphs are used for categorical data representation.
