Question

1. identify the independent variable and dependent variable for each of the graphs in model 3.

graph d
independent variable: hand - written: color
dependent variable: hand - written: # of candies
graph e
independent variable: hand - written: leg length
dependent variable: hand - written: sprint time

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 d
b. “does the length of a person’s leg affect the time it takes them to sprint 60 yards?” - graph e

1. why was the data for graph d plotted in a bar graph? hand - written: its a categorical data. s. m fk
2. using the graphs in model 2 and model 3 as examples of proper graphs, identify the axis (x or y) where you would usually plot the independent variable.

Explanation:

Step1: Identify variables for Graph D

The independent variable is the color of the candy (blue, brown, green, orange, red, yellow) as it is the variable that is being changed or selected. The dependent variable is the average number of candies in the bag as it is the variable that is being measured and depends on the color of the candy.

Step2: Identify variables for Graph E

The independent variable is the leg - length (in cm) as it is the variable that can be controlled or changed. The dependent variable is the sprint time (in sec) as it is the variable that is being measured and is likely affected by the leg - length.

Answer:

For Graph D:
Independent variable: Color of the candy
Dependent variable: Average number of candies in the bag
For Graph E:
Independent variable: Leg - length (cm)
Dependent variable: Sprint time (sec)
