Many people require more than one attempt to pass the driving test for a

driver's license.
The dot plot gives the number of times 21 people took the driving test in
order to earn their driver's license.

Answer : Based on the given dot plot, we can describe the distribution of the number of tests taken as follows:

Shape: The distribution of the number of tests taken appears to be approximately symmetric, with a peak around the middle values. This is indicated by the dot plot being relatively evenly distributed on both sides of the median.

Center: The median of the number of tests taken can be determined by finding the middle value. In this case, there are 21 people, so the median would be the value in the 11th position when the data is arranged in order. Since the values are not provided, it is not possible to determine the exact median from the given information.

Spread: The range of the number of tests taken is the difference between the maximum and minimum values in the data set. However, the specific values are not provided in the dot plot, so the range cannot be determined from the given information.

In summary, based on the information provided, we can determine that the distribution of the number of tests taken appears to be symmetric, but we cannot determine the exact median or range without the specific values of the data set.

Based on the given dot plot, we can describe the distribution of the number of tests taken in the following way:

Shape: The distribution of number of tests taken is skewed to the right. This means that there are more people who passed the driving test on their first or second attempt, and fewer people who required more attempts.

Center: The median of the number of tests taken is 2. This means that half of the people passed the driving test in two or fewer attempts, and the other half passed the driving test in three or more attempts.

Spread: The range of the number of tests taken is 5 tests. The smallest number of tests taken is 1 and the largest number of tests taken is 6.
