Question

What are the mean, median, and mode for the following data set?

Answer 1

Order the number:
15,34,71,75,75,78,78,78,82,90,90,94,100
Mode:78
Mean≈74.8
Median:78 is your final answer. Hope it help!

Answer 2

Answer:

Mean=74.78

Median=78

Mode=78

Step-by-step explanation:

1. First order the data set from the from least to greatest:

15    34    71    75    75    78    78    78   82    87    90    90    94    100

2. To find the mean, add all the numbers and divide the result by the number of data.

$x=\frac{15+34+71+75+75+78+78+78+82+87+90+90+94+100}{14}$

$x=\frac{1047}{14}$

3. Since you have an even data set, to find the median you take the two values of the middle of the data set and find the average between them:

$median=\frac{78+78}{2}$

$median=\frac{156}{2}$

$median=78$

4. The mode is the most repeated value, in this case, value 78 is repeated 3 times so this value is the mode of the data set.
