Consider the following data set giving the pulse rates (in beats per minute) of a random sample of ten students enrolled in a Statistics class
76 60 60 81 72 80 68 73 80 60
Find the following values for the given sample data. You may use a calculator.
a. Mean __________
b. Median __________
c. Mode __________
d. Inter Quartile Range__________
e. Standard deviation __________
f. Outliers __________
Solutions
Expert Solution
a)
mean = ΣX/n = 710.000
/ 10 = 71.0000
b)
Median=0.5(n+1)th value = 5.5th value
of sorted data
= 72.500
c)
mode= highest frequency data = 60
d)
quartile , Q1 = 0.25(n+1)th value= 2.75th
= 60
Quartile , Q3 = 0.75(n+1)th value= 8.25th
= 80
IQR = Q3-Q1 = 20
e)
sample std dev = √ [ Σ(X - X̄)²/(n-1)] =
√ (664/9) =
8.5894
f)
1.5IQR = 30
lower bound=Q1-1.5IQR= 30
upper bound=Q3+1.5IQR= 110
outlier =values outside lower bound and upper
bound
total outlier below lower bound= 0
total outlier above upper bound= 0
total outlier = 0
