Changing the Intervals and Scale on a graph Grade 6 Data Management Unit
Re-cap • What is the purpose of a double bar graph? • What are ways we could separate data in this class?
Intervals • Intervals are the distance between two points on a graph, chart, plot, or grid • Where are the intervals on this graph?
Think, Pair, Share • Re-create this bar graph in your groups by increasing the intervals. • What do you notice happens to the appearance of the graph when you increase the intervals? • What do you think would happen if you decrease the intervals?
scale • The horizontal scale across the bottom and the vertical scale along the side of a graph tell us how much or how many. • What is the scale on this graph?
Think, Pair, Share • In your Math groups, look at the scale. If you were to change the scale from kilometres to metres, what would happen to the appearance of the graph?
Task • Refer to the double bar graph you created for homework. • Re-create your graph by increasing the intervals on the graph through this website: • http://nces.ed.gov/nceskids/createagraph/default.aspx • What has happened to the appearance of your graph in comparison to the original
