Question

The number of hours a group of contestants spent preparing for a quiz show are listed below. What is a frequency table that represents the data?

60 25 86 56 45 48 90 75 30 67 90 36 80 15 32 65 61

Answer 1

Hey!

The first step is to understand what exactly a frequency table is. A frequency table is a list of elements ordered from least-to-greatest, with each element assigned a corresponding occurrence rate. So, let's say I have the following numbers:

0, 2, 4, 3, 3, 5, 9, 8, 7, 7, 7, 9, 10, 8, 3, 2

I'd want to arrange these by using a frequency table, right? Right. So let's see how we can do this.

First, I'll search the list of numbers for the smallest value, which we can see is 0. Then I'll find the next smallest number, which appears to be 2. Next smallest is 3, etc. Eventually I'll rearrange the entire list so that the numbers appear in the least-to-greatest order:

0, 2, 2, 3, 3, 3, 4, 5, 7, 7, 7, 8, 8, 9, 9, 10

Great! Next, I'll want to catalog the number of times that each value in our list has popped up. 0 has popped up 1 time. 2 has popped up 2 times. 3 = 3 times. 4 = 1 time, and so on. Knowing this, we will construct a list that addresses the number of times these values have appeared. The attachment in my comment is the completed table. The list on the right is the number of occurrences of these values, and the list on the left is the list of values themselves.

Now you may understand these frequency tables a bit more. But I'll give you some pointers to make solving your problem a bit easier!

First, take your list and make it less intimidating by organizing its elements from least-to-greatest. Next, log down the number of times each number occurs in the list of elements.
