Eye Colour Pictograph Findings

Thirteen children have blue eyes, 7 have  brown and 2 have green eyes.

Twenty two children were surveyed.

There were no grey eyes in Room 16.

The difference between the least and the most was eleven.

Over half the class has blue eyes!

Statistics - Graphs

Today we learnt about tally charts and pictographs.  We surveyed ten class members and asked them this question...
What colour eyes do you have?
We recorded our data on a tally chart.
We also wrote a title for our pictographs.
Tally Charts
Tally charts help us collect and organise data. The data in a tally chart should be clear and displayed in easy-to-count groups of five.

Pictographs

Pictographs use pictures to represent data, making it easy to compare data visually. To read a pictograph, you start by looking at the key to see how many of a given item each picture stands for. Over the next weeks we will use a key with a scale of one, two, or five, meaning each picture represents one, two, or five of that item.

Tomorrow we will post some photos of our work.

Pie Graphs

Today we learned to do pie graphs. We used a programme called Create A Graph to make our graph. We ddi a class tally chart of Room 16s favourite colours.
