Question

1. a class recorded the number of books each student read this month. use the dot plot below to find the mean, median, mode, and range. dot plot - books read number of books read data values: 0,1,1,1,1,2,2,2,2,2,3,3,3,3,4,4,5 find the: a) mean: b) median: c) mode: d) range:

Explanation:

Step1: List data values

Data: 0,1,1,1,2,2,2,2,3,3,3,4,4,5 (count=14)

Step2: Calculate mean

Sum = 0+1+1+1+2+2+2+2+3+3+3+4+4+5 = 33
Mean = $\frac{33}{14} \approx 2.36$

Step3: Find median

Sorted data, middle 7th & 8th values: 2 & 2
Median = $\frac{2+2}{2}=2$

Step4: Identify mode

Most frequent value: 2 (appears 4 times)

Step5: Compute range

Max - Min = 5 - 0 = 5

Answer:

a) $\approx 2.36$
b) 2
c) 2
d) 5
