Answer:
No Outlier for the given data.
Step-by-step explanation:
The given set of data : 71, 74, 78, 79, 79, 80, 82
Before find the outliers, let's find the median, Lower quartile (Q1) and Upper quartile (Q3).
The given set of data is odd set of data.
So, median = Middle value of the data = 79
Q1 = Median of the lower part.
That is median of 71, 74, 78
So Q1 = 74
Now let's find Q3 which is median of the upper set of data 79, 80, 89
So Q3 = 80
Now let's find Outlier.
Outlier should be more than 1.5 times of Q1 and 1.5 times of Q3
1.5*Q1 = 1.5 * 74 = 111
1.5 Q3 = 1.5*80 = 120
There are no such numbers in the given data.
Therefore, No Outlier for the given data.
