GCSE Secondary Maths Age 13-17 - Probability & Statistics: Scatter Diagram - Explained

The video tutorial explains how Katie measured the length and width of pine cones to create a scatter graph. It discusses potential improvements to the graph by adjusting the axes to eliminate empty space. The tutorial also identifies an outlier in the data, explaining how it differs from other data points, specifically noting its length and narrow width compared to other pine cones.

What does the horizontal axis represent in Katie's scatter graph?

• The width of the pine cones

• The height of the pine cones

• The length of the pine cones

• The number of pine cones

What is one suggested improvement for Katie's scatter graph?

• Adding more data points

• Using a different type of graph

• Changing the color of the graph

• Starting the axes at higher values

Why is it suggested to start the axes at higher values?

• To remove unnecessary empty space

• To make the graph more colorful

• To include more data points

• To change the graph type

What is an outlier in the context of Katie's data?

• A data point that is outside the trend

• A data point that is missing

• A data point that is the average

• A data point that fits the trend

How does the outlier pine cone differ from the others?

• It has a smaller length

• It has a larger width

• It has a larger length

• It has a smaller width
