Question

Part 1: [4 points] Find the measures of central tendency (mean, median, mode and range) for the following data set: 14, 27, 24, 29, 28, 25, 14, 26

Part 2: [3 points] Tell which of these measures would best represent the whole data set and why.

Answer 1

get them in numerical order first

Answer 2

14,14,24,25,26, 27,28,29

Answer 3

Ok .

Answer 4

Mean= average.
add together all the values, and divide by the number of values.
14+14+24...=187

Answer 5

since there are 8 numbers, divide 187 by 8
23.375
mean=23.375

Answer 6

what about the median and range and mode ?

Answer 7

median=middle number

to find the number in the middle, start with one finger at each end and begin crossing numbers off.
for every number you cross of on the right side, you should do one on the left,
and that will eventually bring you to the middle number.

Answer 8

ur left with 25,26 in the middle. find the average of those two.
25+26/2=25.5
median=25.5

Answer 9

mode=most.
which number occurs the most times in this set?
answer=14
mode=14

Answer 10

range ?

Answer 11

Range= biggest number in ur set minus the smallest number
29-14
15
Range=15

Answer 12

Okay what about for part 2 ?

Answer 13

mean=23.375
median=25.5
mode=14
range=15

Answer 14

which number best represents the whole set?

Answer 15

yes .

Answer 16

Not the mode or the range, because they're way too low

Answer 17

so the median ?

Answer 18

so you're stuck between the median and the mean.
Use your own judgement

Answer 19

do i add ? or multiply ?
