Question

1. The number of hours you spent studying each day last week was as follows:

Monday – 2     Tuesday – 1     Wednesday – 3     Thursday – 2     Friday – 1

What is the mean number of hours that you spent studying? _______

What is the mode? _______

What is the median? _______

Which measure of central tendency is most descriptive for this question? ______________

Answer 1

The number of hours you spent studying each day last week is as follows

Monday-2

Tuesday-1

Wednesday-3

Thursday-2

Friday-1

So, the frequency distribution is

Number oF hours	Frequency
1	2
2	2
3	1

Question a

The mean number of hours

=(2+1+3+2+1)/5

=9/5

=1.8

So, the mean number of hours spent studying, is 1.8.

Question b

The mode is the number of hours that occur the most number of times.

Now, 2 hours occurs 2 times; and 1 hour also occurs 2 times.

So, the mode is both 1 and 2.

Question c

The median is the hours, that occurs the middlemost position.

So, the median is 2.

Question 3

The best value of central tendency is the mean; because it is a quantitative data.
