- Find the median. 5.5
- Find the mode. 4
- Find the range. 10
- Find the first and third quartiles. Do not include the median as part of either the lower or the upper half of the data.
- Find the difference between and . 5
- If UCLA had 16 NBA players, will the median or mean change? Explain. The median would not change as the order of the numbers or amount of universities with the same number of players doesn’t change. The mean will change as the sum of all the numbers in the set (or the number of players from the different universities) will change, causing the mean to change.
- If Ohio State had 10 NBA players, would the and change? And how would the graph change? Explain each. The third quartile will change as Ohio state is in the upper half of the data, above the median. This would then cause the graph to stretch slightly to the left, as the third quartile would change.
