$\left(a\right)$ The number of letters for different areas in a postman's bag.
$\left(b\right)$ The height of competitors in an athletics meet.
$\left(c\right)$ The number of cassettes produced by $5$ companies.
$\left(d\right)$ The number of passengers boarding trains from $7:00$ a.m. to $7:00$ p.m. at a station.
Give reasons for each.

• A. $a$
• B. $c$
• C. $b$
• D. $d$

Answer 1

Answer: (C), (D)

Histograms are a special form of bar chart where the data represents continuously rather than discrete categories. This means that in a histogram there are no gaps between the columns representing the different categories.

The height of competitors are continuous data. There are no gaps between the data.

Even the train timings are continuous data.

Hence, option B and C are correct.
