Level 4

Data Handling

You can collect information and put it into a tally table. You can write the frequencies from the tally table. You can work out the Mode and Range for sets of data. You can put data into groups and draw the frequency diagram ( bar chart ). You can understand what the diagrams mean. You can draw your own simple versions of line graphs.

Level 5

Data Handling

You can work out and understand the Mean of a group of data. Compare two groups of data using Mean, Mode, Median and Range. You can explain what graphs and diagrams mean, including pie charts. Use the probability scale from 0 to 1. You can work out probabilities, understand equally likely outcomes and results from experiments. You should know that if you do an experiment more than once you may get different results.

Level 6

Data Handling

Collect and record continuous data. Put data into groups and draw frequency tables. Draw and make comments on frequency diagrams. Draw pie charts. Draw up and comment on scatter graphs and types of correlations. If working with combined probabilities ( e.g. rolling a dice and flipping a coin) you can work out and describe all the different outcomes.

Level 7

Data Handling

Think up a prediction and then check to see if it is true/untrue by collecting information. Write comments on your findings. When data is in groups, work out the modal class and estimate the mean, median and range. Pick the appropriate one of these for the problem you are solving.  Draw lines of best fit onto scatter graphs. Work out and understand relative frequency from experiments.

Level 8

Data Handling

Draw up cumulative frequency tables and graphs. Use CF graphs to work out the median and inter quartile range. Use this information to compare two sets of data both numerically and in words.
