Question

Find the a) mean, b) median, o) mode, d) midrange for the given sample data and answer the given question 1. A sample of twenty-two students midterm exam grades were recorded from a Statistics class last semester. Their grades were: 80, 56, 50, 88, 61, 71,81,96, 78, 100, 68, 54, 81,92, 70, 40, 78, 95, 68, 84,76,79 a) Find the mean () Answer b) Find the median (x) Answer c) Find the mode Answer d) Find the midrange Answer Researchers collected body temperature readiogs from a sample of eight adults. Below are the temperature readings (all in degrees Fahrenheit): 98.6, 98.6,98.1, 99.2, 98.3, 98.4,98.5,98.7 2. a) Find the mean() Answer- b) Find the median () Answer c) Find the mode Answer d) Find the midrange

Explanation / Answer

putting above in ascending order

:

a)mean =total/n =1646/22 =74.82

b) median =(n+1)/2 th value =(22+1)/2 th value =11.5 th value =(78+78)/2 =78

c)mode =68 ,78,81 (as thses values appear maximum 2 times in above data)

d) midrange =(max+min)/2 =(100+40)/2 =70

2)

a) mean =total/n=788.4/8=98.55

b) median =(n+!)/2 th value =4.5th value =(98.5+98.6)/2 =98.55

c) mode =98.6  

d)midrange =(max+min)/2 =(99.2+98.1)/2=98.65

x 40 50 54 56 61 68 68 70 71 76 78 78 79 80 81 81 84 88 92 95 96 100
