a.
To calculate:Mean
a.
Answer to Problem 29PR
The mean value of the data set is 84.0625
Explanation of Solution
Given information:
Number of terms= 16
Used formula:
Calculation:
The mean of a data set is the sum of the terms divided by the total number of terms. Using math notation, we have:
Sum of term
Number of terms= 16
b.
To calculate: Median
b.
Answer to Problem 29PR
The median value of the data set is 87
Explanation of Solution
Given information:
Number of terms= 16
Calculation:
The median is the middle number in a sorted list of numbers. So, to find the median, we need to place the numbers in value order and find the middle number.
Ordering the data from least to greatest, we get:
As you can see, we do not have just one middle number but we have a pair of middle numbers, so the median is the average of these two numbers:
The median
c.
To calculate: Mode
c.
Answer to Problem 29PR
The mode value of the data set is 92
Explanation of Solution
Given information:
Number of terms= 16
Calculation:
The mode of a set of data is the value in the set that occurs most often.
Ordering the data from least to greatest, we get:
We see that the mode is 92.
d.
To calculate: Range
d.
Answer to Problem 29PR
The range value of the data set is 64
Explanation of Solution
Given information:
Number of terms= 16
Calculation:
(iv) The range is the difference between the highest and lowest values in the data set.
Ordering the data from least to greatest, we get:
The lowest value is 36.
The highest value is 100.
The range
e.
To calculate: Standard deviation
e.
Answer to Problem 29PR
The standard deviation value of the data set is s: 14.951875927455
Explanation of Solution
Given information:
Number of terms= 16
Used formula:
Calculation:
f.
To calculate: Outliers
f.
Answer to Problem 29PR
There outlier is 36.
Explanation of Solution
Given information:
Number of terms= 16
Calculation:
There have outliers 36 because 36 have common number in the given question.
