Find the mean of the following data. 34, 23, 10, 45, 44, 47, 35, 37, 41, 30, 28, 32, 45 and 39

Mean is 35

Solution

Mean = Sum of all observations/Number of observations

Mean = (34+23+10+45+44+47+35+37+41+30+28+32+45+39)/ 14

Sum = 490

Mean = 490/14

∴ Mean = 352

The heights (in centimeter) of 10 students in a class are 110, 122, 128, 112, 129, 118, 130, 118, 134 and 120. Find the range of the heights.

Range of the heights of students is 24 centimeter

Solution

Range = Highest observation(Max)-Lowest observation(Min)

Highest observation (Max)=134,

Lowest observation (Min)=110.

Range = (134-110) centimeter

∴ Range of the heights of students is 24 centimeter

Highest observation (Max)=134,

Lowest observation (Min)=110.

Range = (134-110) centimeter

∴ Range of the heights of students is 24 centimeter

Mode = observation that occurs most often.

Arranging the numbers with same values together we get

20, 22, 22, 22, 23, 23, 23, 26, 29

23 and 22 occurs most number of times

∴ Mode = 23 and 22
