How could I find the mean of each set of numbers which is 21,25,27,32,36,37,43,43,44,51
How can I find the median of each set of numbers which is 26,71,33,69,71,25,75
And also how can I find the mode of each set of numbers 9,8,10,9,9,10,8
Mean = sum of scores/number of scores
Median = 50th percentile. Arrange scores in order of value. Middle-most score is median. If two middle-most scores, use their mean.
Mode is most frequently observed score.
but do i have to add then divide,how can i get the numbers? by multiplying?
If you want to post what you think the mean, median, and mode are now, we can check your answers for you.
okay thanks Jen, because the math questions I 've asked earlier, I don't really know what to do either add or divide the number to get the right number
Study this site -- it finding these answers will be easy.

To find the mean of a set of numbers, you need to add up all the numbers and then divide the sum by the total count of numbers in the set. Let's find the mean for the first set of numbers:
1. Add up all the numbers:
21 + 25 + 27 + 32 + 36 + 37 + 43 + 43 + 44 + 51 = 359
2. Count the total number of numbers in the set, which is 10.
3. Divide the sum by the count:
359 / 10 = 35.9
Answer: The mean of the set {21, 25, 27, 32, 36, 37, 43, 43, 44, 51} is 35.9.
To find the median of a set of numbers, you need to arrange the numbers in ascending order and then find the middle value. Let's find the median for the second set of numbers:
1. Arrange the numbers in ascending order:
25, 26, 33, 69, 71, 71, 75
2. Since there are 7 numbers in the set, the median will be the fourth number (if we count from 1) or the average of the two middle numbers.
3. Find the middle value:
The fourth number is 69.
Answer: The median of the set {26, 71, 33, 69, 71, 25, 75} is 69.
To find the mode of a set of numbers, you need to identify the number(s) that appear most frequently. Let's find the mode for the third set of numbers:
1. Count the frequency of each number:
8 appears twice,
9 appears three times,
10 appears twice.
2. Identify the number(s) with the highest frequency:
In this case, the number 9 appears most frequently.
Answer: The mode of the set {9, 8, 10, 9, 9, 10, 8} is 9.
