Draw a tally mark tables also find
a) mean B) median C) mode​

Answer 1

Step-by-step explanation:

Mean - 140/30=4.6

Median= 4

Mode = 4

Answer 2

Answer:

Mean = 4.6

Median = 5

Mode = 4

Step-by-step explanation:

$Mean \: = \: \frac{sum \: of \: all \: observtion}{no. \: of \: all \: observation}$

$Mean \: = \: \frac{140}{30}$

$Mean \: = \: 4.6$

$Median \: = \: \frac{sum \: of \: two \: middle \: observation}{2}$

$Median \: = \: \frac{8 + 2}{2}$

$\: \: \: \: \ \ \: \: \: \: \: \: \: \: \: \: \: \: = \frac{10}{2}$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 5$

$Mode \: = \: the \: observation \: which \: occurs \: maximum \: no. \: of \: time$

$Mode \: = \: 4$
