Objective:
The purpose of this video is to introduce the first part of statistics which is collecting data using a tally count. This count is then converted into a frequency table which is much easier to read.Help on this Topic:
A frequency table is where we write down HOW OFTEN something happens.
Lets have a look at an example question
John throws a die 40 times.
The results of each throw were written down as follows:
Value on face of die: 4,1,2,1,2,4,1,1,4,1,6,6,1,6,2,2,2,2,5,1,1,4,4,3,2,3,2,2,3,5,4,2,4,1,4,5,5,4,6,2,,
The data was sorted into the following frequency table
| Die value | 1 | 2 | 3 | 4 | 5 | 6 |
| Frequency | _ | _ | _ | _ | _ | _ |
List the missing numbers from the table (from left to right).
Seperate your answers with commas
In this question we are asked for the frequency of 1s, the frequency of 2s and so on. This is asking, how many times did I get a 1 and put it in the first place, ow many times did I get a 2 and so on.
In this question we count all the ones (9), twos (11), threes (3), fours(9), fives (4), sixes (4)
We add all these numbers up 9+11+3+9+4+4 = 40 to make sure that they add up to 40. This helps me not make a mistake.
Then I enter my answer. 9,11,3,9,4,4
