Answer 1

Answer:

PLS MARK ME AS THE BRANLIEST

Mean= 76.95

Median= 79

Mode= 95

Step-by-step explanation:

MEAN

No.of observations= 20

Sum of all observation= 75+62+88+55+90+95+85+69+62+78+90+95+90+95+80+71+44+57+68+90= 1539

Mean= No.of observations/Sum of all observation=

1539/20 = 76.95

MEDIAN

Arrange in asending or desending order. If the no.of observation is odd the median is middle most number and if even the sum of two middle most numbers divided by 2

44, 55, 57, 62, 62, 68, 69, 71, 75, 78, 80, 85, 88, 90, 90, 90, 90, 95, 95, 95 Here the no. of observation is even. So the middle most number is 78 and 80.

The median is 78+80/2 = 79

MODE

The highest frequency is mode.

44 = 1

55 = 1

57 = 1

62 = 2

68 = 1

69 = 1

71 = 1

75 = 1

78 = 1

80 = 1

85 = 1

88 = 1

90 = 4

95 = 3

So, mode is 95
