Statistical Representation of Data

Question : 17 of 57

Marks: +1, -0

Solution:

Concept:

Frequency density is the frequency per unit class width.

Explanation:

The second class interval is

49-53

Since the intervals are inclusive (e.g.,

48

49

have a gap of

1

), the class width is calculated as upper limit minus lower limit plus

1

So, width

= 53 - 49 + 1 = 5

Frequency

= 5

Frequency density

= \frac{\text{Frequency}}{\text{Class width}} = \frac{5}{5} = 1.00

Answer:

1.00
