Mrs. Coburn-mean, Median, Mode, Quiz

The mean is calculated by adding up all the numbers and then dividing the sum by the total number of values. In this case, the sum of the test results is 526, and there are 6 values. Dividing 526 by 6 gives us an average of 87.

The mode is the value that appears most frequently in a set of data. In this case, the number 15 appears twice, which is more than any other number, making it the mode. The mean is the average of all the numbers in the set. To find the mean, we add up all the numbers and divide by the total count. In this case, the sum of all the numbers is 115 and there are 5 numbers, so the mean is 115/5 = 23. An outlier is a value that is significantly different from the other values in the set. In this case, the number 75 is much larger than the other numbers, making it the outlier.

To find Manny's average, we add up all his Habits of Work scores and divide by the number of scores. In this case, the sum of the scores is 2.0 + 1.5 + 4.0 + 1.0 + 4.0 + 4.0 = 16.5. Since there are 6 scores, the average is 16.5 / 6 = 2.75. Therefore, the correct answer is "No his average is a 2.75."

The median of a set of data is the middle value when the data is arranged in ascending or descending order. In this case, when the data is arranged in ascending order, it becomes 2, 4, 4, 6, 7, 9, 13. The middle value is 6, so the median is 6.

The range of a set of data is the difference between the maximum and minimum values. In this case, the maximum value is 13 and the minimum value is 2. The difference between them is 11, so the range is 11.
