Question

Calculate mean,median,mode from the data given below of the hieghts (in inches) of a group of students 60,62,61,63,64,63,61,64,65,63,64,66,64

Answer 1

Answer:

MEAN=63.15

MEDIAN=63

MODE=63

Step-by-step explanation:

ASCENDING order=

60,61,61,62,63,63,63,64,64,64,64,65,

MEAN=

SUM OF OBSERVATIONS/NUMBER OF OBSERVATIONS

Sum=60+61+61+62+63+63+63+64+64+64+64+65+67

=821

Total Number of observations=13

MEAN=821/13

=63.15

THEREFORE, MEAN=63.15

MEDIAN=

Middle most observation

Ascending order=

60,61,61,62,63,63,63,64,64,64,64,65,66

Here 63 is the middle most observation.

THEREFORE, MEDIAN=63

MODE=

MOST REPEATING OBSERVATION

60,61,61,62,63,63,63,64,64,64,64,65,66

HERE 63 IS REPEATING 4 TIMES WHICH IS HIGHEST.

THEREFORE, MODE=63
