Answer

Explanation:

Step1: No data values given

Since we are not provided with the actual data values in cells A1 - A20, we cannot calculate the exact sum, mean and median. In a real - world spreadsheet scenario, if we had the data, the sum formula =Sum(A1:A20) adds all the values in the range A1 to A20. The mean formula =Mean(A1:A20) divides the sum of the values in the range A1 to A20 by the number of values (20 in this case). The median formula =Median(A1:A20) finds the middle value when the data in the range A1 to A20 is sorted.

Step2: Analyzing effect of changing A1

If we change the value in A1 to 8, the sum will change by the difference between the original value in A1 and 8. The mean will also change because the sum (numerator in the mean calculation) changes while the number of data points (denominator) remains 20. The median may or may not change depending on the position of A1 in the sorted list of values from A1 to A20. If A1 was not in the middle - most positions in the sorted list, the median may remain the same.

Answer:

  1. Without data values in A1:A20, we cannot determine the sum, mean and median values.
  2. Changing A1 to 8 will change the sum and likely the mean. The effect on the median depends on the original position of A1 in the sorted data set.
