Answer:
Explanation:
The median is the middle value of a set of data, and the mode is the value that appears most often.
For example:
1. The values given are: 6, 9, 2, 4, 3, 6, 5
To find the median, we have to list the numbers in order from smallest to largest.
2, 3, 4, 5, 6, 6, 9
Then, cross out a number on the left and on the right. Repeat this process until only one or two numbers are not crossed out.
In this case, all of the numbers except for 5 are crossed out.
This means that 5 is the median.
To find the mode, all we have to do is see which number appears the most. In this set of number, the number 6 appears twice, more than any other number.
So, the mode is 6.
You can do the same thing for the other problems.
To find the mean of a set of values, you have to add all of the numbers together and divide them by the total amount of numbers in the set.
For example:
7. There are 8 numbers in this set. These numbers are:
21, 23, 27, 28, 32, 32, 34, 43
First, we have to add all of the numbers together.
21 + 23 + 27 + 28 + 32 + 32 + 34 +43 = 240
Now, we have to divide 240 by 8(the total amount of numbers in the set)
240/8 = 30
The mean is 30.
