From the frequency distribution table from the following data

Here, we observe that, all 34 students have scored marks more than or equal to 0. Since, 32 students have scored marks more than or equal to 10. So, 34 – 32 = 2 students lies in the interval 0 - 10 and so on.

Now, we construct the frequency distribution table.
