What is the mean mediam and mode for 64,75,62,90,81,52,80,99,100,65,75,61,0,106,72,70,80,92,90,102

Mean = Σx/n (add all the scores and divide by the number of scores)

Median = 50th percentile (arrange scores according to value, find value that half of the scores are above and half below. If it is in between two scores, find the mean of those two scores.

Mode = most frequently observed score. A distribution can have no or more than one mode.

Now you should be able to do the calculations.

To find the mean, median, and mode of the given set of numbers, follow these steps:

1. Mean: The mean is calculated by summing all the numbers together and then dividing the sum by the total number of values.

Sum of all the numbers = 64 + 75 + 62 + 90 + 81 + 52 + 80 + 99 + 100 + 65 + 75 + 61 + 0 + 106 + 72 + 70 + 80 + 92 + 90 + 102 = 1666

Total number of values = 20

Mean = Sum of all the numbers / Total number of values = 1666 / 20 = 83.3

Therefore, the mean of the given set of numbers is 83.3.

2. Median: The median is the middle value when the numbers are arranged in ascending order. If there is an even number of values, then the median is the average of the two middle values.

First, let's arrange the numbers in ascending order: 0, 52, 61, 62, 64, 65, 70, 72, 75, 75, 80, 80, 81, 90, 90, 92, 99, 100, 102, 106

As there are 20 values, the middle two numbers are the 10th and 11th numbers: 80 and 81.

Median = (80 + 81) / 2 = 161 / 2 = 80.5

Therefore, the median of the given set of numbers is 80.5.

3. Mode: The mode is the number that appears most frequently in the set of numbers.

In the given set of numbers, we can see that 75 and 80 both appear twice, while all other numbers appear only once. Therefore, the modes of the given set of numbers are 75 and 80.

To summarize:
- Mean = 83.3
- Median = 80.5
- Mode = 75, 80
