Copy and paste your table of results into a spreadsheet then investigate the following:

• What is the average time it took you to make your estimate?
• Is your estimate more likely to be higher or lower than the actual distance?
• Is there a correlation between the distance and your percentage error?
• Can you work out the formula the computer uses to calculate your score?
• Can you get better at estimating with practice?
