Question

find mean median mode of last 15 days weather report that is shown in the below and on a bar graph of the data

Answer 1

$sigma \: x = sum \: of \: all \: no.s \: \div the \: total \: no. \: of \: events \: or \: anything \\ so \\ 32 + 32 + 33 + 32 + 31 + 31 + 32 \div 7 = 164.42$
Then see that mode is the no. of interval which repeats the most and we see that 32 has the highest no. Of repeating
Therefore,
Mode = 32
Then,
To find median we see that no. Of events is odd i.e 7,
Median = 31, 31, 32, 32, 32, 32, 33
If you observe carefully you will see that in the middlemost term 32 is present that is
Three lower than the front ones and three higher than the lower ones
So,
Median = 32
Or,
By formula,
(N/2th)+1 term,
=7/2+1=4,
So, there is your answer
