Question

the eight cats in a pet store were weighed. their weights (in pounds) are given in the dot - plot below. (a dot plot is shown with weight (in pounds) on the vertical axis. there are dots at 1, 3 (4 dots), 5, 7 (2 dots).) find the mode and the range for the data. (a) mode: (b) range:

Explanation:

Step1: Recall mode definition

The mode is the value that appears most frequently in a data - set.

Step2: Identify mode from dot - plot

From the dot - plot, the value 3 has 4 dots (more than any other value). So the mode is 3.

Step3: Recall range definition

The range is the difference between the maximum and minimum values in a data - set.

Step4: Find maximum and minimum values

The minimum value from the dot - plot is 1 and the maximum value is 7.

Step5: Calculate the range

Range = Maximum value - Minimum value = 7 - 1=6.

Answer:

(a) Mode: 3
(b) Range: 6
