The frequency is the number of times an event occurs; or the number of individuals (people, animals etc.) with some specific property.

A pictogram (pictograph) is a graph consisting of pictures to visually represent the frequency of objects or groups

Interpreting scatter graphs

Problem solving with graphical representations of data

In this unit, pupils explore different graphs and charts as a way of presenting data visually. Pupils are introduced to scatter graphs and learn how to construct them in this unit. In the future unit, this understanding is extended to using a line of best fit to allow interpolation

In this unit, pupils interpreted and constructed pie charts based on their understanding of fractions and proportion

In this unit pupils will interpret and construct a range of representations of data including bar charts, pie charts and scatter graphs.

Graphical representations of data

This type of representation is known as a {{ }}.

A pictogram is going to be drawn where each icon represents a frequency of 4. How many icons would be needed to show a frequency of 32?

{{}} need to be fairly simple in design and representative of the data.

Izzy, Sam and Jacob have 24 pens between them. Therefore each icon represents {{ }} pens.

Which frequency table matches this pictogram?

Plant 3 had 45 leaves fewer than plant 1.

Which of these statements are true for the data shown in this pictogram? (IMG: )

The frequency is the {{ }} of times an event occurs; or the {{ }} of individuals (people, animals etc.) with some specific property. 

The chart shows how many times some zoo animals were seen in an hour. The {{ }} was seen 9 times.

What is $${{\frac {1} {4}} \times 20}$$ ?
