Question

Q.4. Define the following terms and give two example
of each term
(i) Raw data
subject : mathematics​

Answer 1

unorganised data is raw data.

examples:

marks of 20 students in maths test

11,4,27,18,18,3,24,22,11,22,18,11,18,7,29,18,11,6,29,11

suppose we want number of student whose marks in 29.

we will have to search for 29 in the numbers and count it.

what if the number of students are more?

if there are hundred students the counting will become difficult.

so so we organise the data using Tally marks.
