I have a chart that has 4 columns across the top and 33 going down. The colunms on the top read: predicted number, selected number, (col 1 - col2)^2, and the mean of x. Their are 32 predicted numbers and 33 selected numbers. I need to fill in the column that says the mean of x but I am not sure how to do this.
Column 1 reads :
5 -2 49
How would I find the mean for this column?
To find the mean of a column, you need to add up all the values in that column and divide it by the total number of values in the column. In this case, column 1 has 33 rows.
To find the mean of column 1 in your chart:
1. Add up all the values in column 1. In this case, 5 + (-2) + 49 = 52.
2. Divide the sum by the total number of values in the column, which is 33.
52 / 33 = 1.575 approximately.
So, the mean of column 1 in your chart is approximately 1.575.
