To find: How does subtracting the same amount from each value in the data set affect the mean, median, mode, and range.
Answer to Problem 25PPE
When same amount is subtracted from each value in a data set the mean, median, and mode also shift left by same amount. But the range remain same.
Explanation of Solution
Given information:
Same amount is subtracted from each value in a data set.
Calculation:
Let us suppose there is a data set
Now let us subtract same amount
New data set would be
Therefore, when same amount is subtracted from each value in a data set the mean, median, and mode also shift left by same amount. But the range remain same.
