Answer:
10 to 15 (B)
Step-by-step explanation:
Find attached the diagram of the dot plot.
A measure of spread is used to describe the variation in a sample or data set. It is sometimes referred to as a measure of dispersion.
It is usually used together with the mean or median, to provide an overall description of a set of data.
There are two measures of spread: range and standard deviation. Range is the simplest in terms of calculation.
In this question, the range is used to determine the spread of the data set.
From the dot plot,
The range = the highest value - lowest value in a data set.
The highest value = 15
The lowest value = 10
Therefore the spread of the data in the dot plot is from 10 to 15 (B)
