Q 1.3. - The Practice of Statistics for AP

Question

The Fathom dot-plot displays data on the number of siblings reported by each student in a statistics class. 

Describe the spread of the distribution.

Step-by-Step Solution

Answer

The distribution is not approximately normally distributed

Step 1: Given information

The dot-plot is : 

Step 2: Concept

The spread of distribution indicates the amount of variability in the data. Giving the smallest and greatest values is one approach to describe the variability.

Step 3: Explanation

Because the data set's minimum value is $0$and highest value is $6$, the range of the data is obvious from the accompanying graphic. As a result, the range is 6. Two outliers are visible in the presented figure, numbers $5$ and $6$, because they are far apart from the other values in the data set. As a result, the distribution cannot be claimed to be nearly normally distributed.
