Question

The applicants for a soccer coaching position were asked how many years ofcoaching experience they had. Here are the results:1,1,2,2,2,4,4,5,6,6, 8, 8, 8.10On a piece of paper, draw a dot plot to represent the data. Then determinewhich answer choice matches the dot plot you drew.

Answer 1

The dot plot accurately represents the coaching experience data, with the correct number of dots at each value. Choice B matches the drawn dot plot.

The dot plot representing the soccer coaching experience data is as follows:

Each dot in the plot corresponds to a year of coaching experience, and the frequency of each value is represented by the number of dots stacked vertically. In this dot plot, the number of dots at each value accurately reflects the given data: one dot for 1 year, three dots for 2 years, two dots for 4 years, one dot for 5 years, two dots for 6 years, and three dots for 8 years.

This representation allows for a clear visualization of the distribution of coaching experience among the applicants.

Therefore , from the given options the correct one is B.

Answer 2

To draw a dot plot, first, we need to draw a line with all the possible values of the data points. In this case, the values go from 1 to 10.

Next, we need to draw one dot for each appearance of each value. That is, the value 1 appears 2 times in the data set, then 2 dots must be drawn over the number 1 in the plot. Similarly, the value 2 occurs 3 times, then 3 dots must be drawn over the number 2. The value 4 occurs 2 times, then 2 dots are drawn over the 4; the value 5 occurs 1 time, then 1 dot is drawn over the 5; the value 6 occurs 2 times, then 2 dots are drawn over the 6; the value 8 occurs 3 times, then 3 dots are drawn over the 8; and the value 10 occurs 1 time, then 1 dot is drawn over the 10.

The dot plot is:
