Key words Data: information Column graph: Column graphs are an excellent way to show results that aren't continuous - especially samplings such as surveys. Horizontal axis: this is a line running across the graph. It has a label beneath it. Vertical axis: this is a line running up the side of a graph. It has a label next to it. A table is a grid of rows and columns into which data is placed. Scale: The scales on horizontal or vertical axes are similar to the scales found on many measuring instruments. A scale is a series of numbers that are increasing or decreasing by the same amount. Part of the skill of interpreting a graph is reading the scales on the axes. Each scale will be labelled with the unit of measurement that has been used. 2

Use of column graphs A column graph is used to show relationships between groups. Column graphs are an excellent way to show results that are one time, that aren't continuous - especially samplings such as surveys. 4

Origin of the words graph and data 5

How to construct a column graph. 1 -Draw two axes: one vertical and one horizontal. Make sure you leave room at the edge of the page for your labels. 2 - Always place numbers on the vertical axis. Non-numerical groups are on the horizontal axis. 3 - Label each axis. 3 - Columns should be of the same width and should not touch at all 4 - Leave half of the column width at the start. 5 - The scale should go up evenly and cover the largest and smallest values. 6 - Include scientific units where appropriate. 7 - Include a title to explain what the graph is about. Your title should start with: Graph of……. . 6

Things you should follow when drawing a column graph use grid paper Column graphs have a series of vertical blocks. Columns should be of the same width and should not touch at all. Leave half of the column width at the start Always place numbers (numerical groups)on the vertical axis. use a pencil Draw in the two axes with a ruler Non-numerical groups are on the horizontal axis. 7

What is a table? A table is a grid of rows and columns into which data is placed. Column Row A row is a horizontal series of cells, while a column is a vertical series. A table should have: Ø a clear and simple title Ø a set of rows and columns Ø headings for the columns 8

A table should have: Ø a clear and simple title Ø a set of rows and columns Ø headings for the columns. Heart rate after exercise Heart rate Heart beat Time At rest 60 After running 120 2 mins later 100 4 mins later 84 6 mins later 70 8 mins later 64 9 Time

Use the data in the graph to draw a table Decide on the number of columns and rows Using a ruler to draw a grid leaving enough spaces for the data. Write your title at the top of the table Label the columns and the rows Write your data Heart rate after exercise 140 120 100 8 mins later 6 mins later 80 4 mins later 60 2 mins later After running 40 At rest 20 0 At rest After running 2 mins later 4 mins later 6 mins later 8 mins later Heart beat Time At rest 60 After running 120 2 mins later 100 4 mins later 84 6 mins later 70 8 mins later 64 Time 10

This table shows the heart beats of Emma at rest, after exercise and every 2 minutes after exercise. Heart beat Time At rest 60 After running 120 2 mins later 100 4 mins later 84 6 mins later 70 8 mins later 64 Draw a suitable graph for your data 11

Graph of heart rate after exercise Title Add a title Step 1: Draw the axes Step 2: Always place numbers on the vertical axis. Non-numerical group on the horizontal axis. The Vertical axis going up shows frequency (Numbers) Step 3: Label the axis Heart rate Step 4: Setting up the scales. Count how may squares represent 1 on vertical axis. On the horizontal axis, Leave 0. 5 gap for the start (1 square) (half of the column width) 1 cm Step 5: Putting up the values and drawing the columns should be of the same width (1 cm). . 60 50 0 At fte re 2 m xerc in ise us l 4 m ater in sl at er 30 st re Time The horizontal axis (going across) shows the items 14
