Question

1. Find the range of this data set: 225, 342, 288, 552, 263 2. Find the median of this data set: 476, 234, 355, 765, 470 3. Find the mode of this data set: 16 7 8 5 16 7 8 4 7 8 16 7 _______ 4. Find the range of this data set: 64 76 46 88 88 43 99 50 55. 5. Reasoning Would the mode change if a 76 were added to the data in Exercise 4?

Please help!!!

Answer 1

1.Range = highest value - lowest value

R=552-225

R=327

2.Re-arrange the set of the data from ascending order

=234,355,470,476,765

Median is the middle value which is

=470

3. Mode is the most occuring frequency which is

=7

4. 1.Range = highest value - lowest value

R=99 - 43

R=56

5.No the range with not change because 76 is neither the highest nor the lowest value

Note: Range = highest value - lowest value
