Question

how to make table for frequency table​

Answer 1

Answer:

Need to know more of the problem to make this useful for you...probably.   for this step by step i decided to have 5 classes.   you can have as many as you want.

Step-by-step explanation:

Class      Frequency     Relative Frequency     Data

67-68           2                      10%                   67, 67

69-70           7                       35%                 69, 69, 70, 70, 70, 70, 70

71-72             3                       15%                 71, 72, 72

73-74             7                      35%                73, 73, 73, 73, 74, 74, 74

75-76             1                       5%                  75          

totals below

4 Classes      20 occurrences/patients

Relative frequency= frequency/occurrence      

mean= sum of data points / number of occurrences = 1426/20=71.3

mode= most frequently occurring data points= 70

Max= 75

Q1= 70

Median= 71.5

Q3= 73

Standard deviation= 2.341839133

Min= 67

n= number of occurrences= 20
