Concept explainers
(a)
To find the mean, median and mode of data set.
(a)
Answer to Problem 8E
Mean =
Median =
Mode = 14 and 15
Explanation of Solution
Given information:
Formula Used: Mean =
Calculation:
Now, in Ascending Order
- Mean
Mean =
So,
Mean =
Now,
Mean =
Hence,
Mean =
- Median
Median for even numbers =
So,
Median =
Now,
Median =
As,
So,
Median =
Hence,
Median =
- Mode
Mode = Most repeated value.
So,
14 and 15 is the most repeated value.
Mode = 14 and 15
(b)
To find measure of center best represents of data.
(b)
Answer to Problem 8E
Median
Explanation of Solution
Given information: Mean, Median and Mode
Calculation:
Median best describes the central tendency data because the outlier disturbs the mean.
