How do you get the mean of a data set?

Answer 1

there are some cases in calculating mean

1. when only variable is given:

sum of total observations divided by number of observation

2. When discrete series are given:

summation of the product of value of variable and its frequency the divided by summation of frequencies

Answer 2

Add together all the number in the data set.

Count the number of numbers in the data set.

Divide the sum by the number of values. That is the (arithmetic) mean.

If a question simply asks for the mean, it is referring to the arithmetic mean.

To find the geometric mean, count up the number of numbers in the data set and call than n. Multiply all the numbers together and take the nth root.

Answer 3

You first add the data up and then you divide the number you get by how many numbers are in your set data.

For example:

3, 4, 6

Add them up, first. 4+2+6= 12.

Now, divide by how many numbers were in the set of data. There were 3 numbers, so 12/3 equals 4.

why so much you really took your time btw i dont k
