Question

Use the graphs in Figure 3 below to answer the questions.

Select the letter of the appropriate graph (Answer A or B.). Without calculating the standard deviation, which graph represents a data set with the least standard deviation

**Figure 3. Graph A:**

Graph A is a bar chart that represents data for a series labeled as "Series1". The horizontal axis (x-axis) represents numerical data points ranging from 4 to 10. The vertical axis (y-axis) represents the frequency or count, ranging from 0 to 7. The specific values for the bars are as follows:

- At x = 4, the frequency is 6.
- At x = 5, the frequency is 0.
- At x = 6, the frequency is 0.
- At x = 7, the frequency is 0.
- At x = 8, the frequency is 0.
- At x = 9, the frequency is 6.
- At x = 10, the frequency is 6.

There is a noticeable pattern where the values are zero for a sequence of x-values (5 through 8), with higher frequencies observed at the ends (x = 4, 9, and 10).

**Figure 3. Graph B:**

Graph B is also a bar chart representing the same series labeled as "Series1". The horizontal axis (x-axis) presents data points from 4 to 10, and the vertical axis (y-axis) shows the frequency or count from 0 to 7. The specific values for the bars are as follows:

- At x = 4, the frequency is 4.
- At x = 5, the frequency is 5.
- At x = 6, the frequency is 6.
- At x = 7, the frequency is 6.
- At x = 8, the frequency is 5.
- At x = 9, the frequency is 4.
- At x = 10, the frequency is 0.

This chart demonstrates a normal distribution pattern, with frequencies increasing to a peak in the middle (x = 6 and x = 7 with 6 counts each) and decreasing symmetrically on either side.
