Question

Following are the marks of 20 students in mathematics:

91, 63, 54, 83, 92, 63, 75, 85, 89, 91, 63, 72, 83, 54, 92, 75, 84, 90, 91, 83​

Answer 1

Answer:

I think we have to solve it as Tally Marks...

First = We write the numbers in an order...

91, 91, 91, 63, 63, 63, 54, 54, 83, 83, 83, 92, 75, 75, 75, 85, 89, 72...

Now the numbers are in Order...

Create a table like I have shown in the Image...But Don't write the numbers only write the HeadLines like Scores, Tally Marks and Frequency....

The write the first number which is 91 then in Tally Marks option write the numbers of 91 where it's got repeated like how many 91 numbers are there, 3 the write |||... In frequency write 3...

Then 63 is repeated 3times then again write in Tally Marks ||| and In Frequency 3....

I hope you will solve all of that...
