Question

hours of practice this week
the dot plot shows the number of hours students in the
band practiced their instruments.
which describe the dot plot? select all that apply.
□ there is a cluster from 3 to 4.
□ there is a gap between 1 and 3.
□ there is a peak at 4.
□ the data shows symmetry.
□ the data is skewed left.
□ the data is skewed right.

Explanation:

Step1: Analyze cluster

A cluster is a group of data points close together. From the dot - plot, there are multiple dots from 3 to 4, so there is a cluster from 3 to 4.

Step2: Analyze gap

A gap is an interval with no data points. There are no dots between 1 and 3, so there is a gap between 1 and 3.

Step3: Analyze peak

A peak is the value with the most data points. At 4, there are more dots than other values, so there is a peak at 4.

Step4: Analyze symmetry

For symmetry, the data on either side of the center should mirror. The data is not symmetric.

Step5: Analyze skewness

If the tail is on the left, it is skewed left; if on the right, skewed right. Here, the tail is on the left (fewer data points on the left side), so it is not skewed right.

Answer:

There is a cluster from 3 to 4, There is a gap between 1 and 3, There is a peak at 4.
