# Level 3-4 Data Handling - Lists and Frequency Tables

Hey, data handling is a big deal in KS3 Maths, right? Once you've got your info, the next cool step is analysing it! There are loads of ways to do this, like using graphs or diagrams. But guess what's super simple and helpful? Lists and frequency tables! They're like the superhero sidekicks to making awesome graphs or diagrams.

1.
In a table recording responses to a questionnaire, each question should be followed by .......
the names of all people taking part in the survey
a space for the frequency of each possible answer
space for working out frequencies
separate spaces for male and female responses
You can create a tally in the space beside each answer
2.
A football league secretary keeps a table of matches won, lost or drawn. How should he list the teams?

In numerical order
Team names are qualitative data so the most sensible order is alphabetical
3.
The secretary puts the results on to a computer spreadsheet to .......
improve team performance
make the table look better
make it easier to update the league table
get the results from teams more quickly
Spreadsheets are excellent tools for analysing continuously changing information
4.
W = games won, L = lost, D = drawn. Which calculation checks the number of games played by a team so far?
W + L - D
D - (W + L)
W + L + D
W - L + D
Each of the team's games will be marked in one of the categories so add them all up to find the total number of games
5.
Which calculation checks the total number of matches played in the league so far?
Add up all the W, L and D values
Add up all the W and L values and divide by 2
Add the total of the W values to half the total of the D values

A drawn match will be recorded twice but all others are either won or lost
6.
2 points for a win, 1 point for a draw, nothing for a loss. Which calculation gives a team's points total so far?
W + L + D
2W + D
2(W + L)
2W + L
Remember, anything times zero is still zero

10%
15%
20%
5 out of 25 is the same as 20 out of 100 = 20%
