Referenced from lesson Measures of Center
Consider the following list dataset, representing the heaviest bench press (in lbs) for ten powerlifters:
135, 95, 230, 135, 203, 55, 1075, 135, 110, 185
1, In the space below, rewrite this dataset in sorted order.
2, In the table below, compute the measures of center for this dataset.
Mean (Average) |
Median |
Mode(s) |
3, The following statements are correct … but misleading. Write down the reason why.
Statement | Why it’s misleading |
---|---|
“More personal records are set at 135 lbs than any other weight!” |
|
“The average powerlifter can bench press 235 lbs.” |
|
“With a median of 135, that means that half the people in this group can’t even lift 135 lbs.” |
