Question

The table given here shows the number of calories contained in one serving of student's favourite cereals.

Number of calories per serving of cereals

$70$	$120$	$100$	$100$	$140$
$70$	$120$	$100$	$100$	$100$
$110$	$100$	$110$	$120$	$100$
$110$	$100$	$100$	$110$	$150$
$90$	$110$	$120$	$110$	$100$
$140$	$130$	$100$	$80$	$100$
$100$	$110$	$80$	$90$	$110$

How many calories are in one serving of most of the cereals?

Answer 1

Step 1: first make a frequency table

To represent the data in frequency tabular form , we make three colimns

Column 1: Arrange all the calories intake by students in ascending order.

Column 2: Write Tally marks.

Column 3: Write the number of students in that particular calories range.

Now, lets make the frequency table

Number of calories per serving of cereals	Tally marks	Frequency
$70$	$\left|\right|$	$2$
$80$	$\left|\right|$	$2$
$90$	$\left|\right|$	$2$
$100$	$\bcancel{\left|\right|\left|\right|}\bcancel{\left|\right|\left|\right|}\left|\right||$	$13$
$110$	$\bcancel{\left|\right|\left|\right|}\left|\right||$	$8$
$120$	$\left|\right|\left|\right|$	$4$
$130$	$|$	$1$
$140$	$\left|\right|$	$2$
$150$	$|$	$1$

Hence, the above tabular form is the frequency table of the given data.

Step 2: Finding calories are in one serving of most of the cereals

As per the frequency table drawn in step 1 it can be clearly seen that $100$ calories per serving of cereals is mostly taken by students.

so, $100$ calories are in one serving of most of the cereals
