Q 1.2. - 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 center of the distribution. 

Step-by-Step Solution

Answer

The centre of distribution in this graph is 2. 

Step 1: Given information

Step 2: Concept

Centre: can be described by selecting a value that divides the observations in half, with the bigger half taking greater values and the smaller half taking lower values. The median of the distribution is this value. The median in Figure 1.9 is 3. That means, during the 2004 season, the US women's soccer team averaged roughly 3 goals per game. For instance, we might calculate the average (mean) of the number of goals scored per game to describe the center of the distribution. The team's average during the 2004 season was 3.06 goals.

Step 3: Explanation

The presented figure shows that the distribution is right-skewed, and the median is, implying that each student has two siblings.
