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 :
predicted # = 5
Selected # = -2
(col 1 - col 2)^2 = 49
How would I find the mean for this column?

To find the mean of a column, you need to calculate the average of all the values in that column. In this case, the column is labeled "mean of x" which means you need to calculate the average of the values in the column.

Since the meaning of the column is not explicitly mentioned in your question, it's unclear what specific values you should consider. However, I can explain how to find the mean in general.

Here's how you can find the mean of a column:

1. Add up all the values in the column. For example, if you have the following values in the "mean of x" column:

3, 6, 1, 8, 4

The sum of these values would be: 3 + 6 + 1 + 8 + 4 = 22.

2. Count the number of values in the column. In your chart, you mentioned that the column has 33 values.

3. Divide the sum of the values by the number of values. In our example, the sum was 22 and the number of values was 5. So the mean would be:

22 / 5 = 4.4

Therefore, the mean of the "mean of x" column in your chart would depend on the specific values in that column. You would follow the steps above using those values to calculate the mean.
