• Mean, median, variance, and standard deviation

How does reducing the lowest value by 10 affect the range of the data set?

• The range becomes zero

• The range decreases

• The range remains the same

• The range increases

What happens to the mean when the lowest value in the data set is decreased by 10?

• The mean increases

• The mean decreases

• The mean remains unchanged

• The mean becomes zero

Why does the standard deviation change when the lowest value is reduced?

• The data set becomes more concentrated

• The data set becomes less spread out

• The data set remains unchanged

• The data set becomes more spread out

Why does the median remain unchanged despite a change in the lowest value?

• The median is recalculated to remain the same

• The median is the middle value and is not affected by changes in outliers

• The median is only affected by changes in the highest value

• The median is not affected by changes in the data set
