Using Excel to Draw a Best Fit Line
Students create line graphs for given data in Microsoft Excel. Students follow step by step instructions on how to create their graph, including how to create a trend line. Students print graphs without trend lines and manually draw...
CCSS Math Activities
Scatter Diagram
Don't let a great resource scatter to the winds. Pupils analyze two sets of test scores on a scatter plot. They draw a line of best fit and use it to make predictions about the test scores. They also consider any apparent trends in the...
