Shedding Light on Graphs and Statistics Vocabulary

Don’t be scared or put off by intimidating terms to do with graphs and statistics. Following is a list of jargon that should shed some light on for you:

• Bar chart: A graph that looks like a city skyline – the height of each bar tells you how many things it represents.

• Line graph: Surprise! A graph with a line on it. How high the line is tells you what value the graph has at that point.

• Mean: The number you get by adding up a list of numbers and dividing by how many numbers there are.

• Median: The middle value in a list.

• Mode: The most common number in a list.

• Pictogram: A graph made of pictures. It works just like a bar chart.

• Pie chart: A circular graph divided into slices. The angle in each slice tells you what proportion of the total it represents.

• Range: The difference between the biggest and smallest number in a list.

• Scatter graph: A graph made up of crosses all over the place – each cross represents an observation, and the numbers on the two axes give its value.

• Tally chart: A table with short vertical lines grouped in sets of five (four lines with one line through them) to make them easier to count.
