Consider this data set:
{49, 50, 45, 23, 35, 66, 34, 74, 54, 50}
The mean increases by ( )
The median increases by ( )
The mode ( )
The range ( )
The mean increases by 2.1 (rounded to one decimal place) if we add 10 to each value in the data set, the new mean is 51.1.
The median remains the same if we add a constant number to each value in the data set. In this case, the median is 49.5.
There is no mode in this data set as each value only appears once.
The range increases by 10 if we add 10 to each value in the data set. The new range is 51 (74-23=51).
