Try this: Predicting reaction time

You will need

  • Copy of the graph above
  • Ruler
  • Pen

Use a line of best fit to make predictions about hand reaction time

  • Place a ruler on the graph so it covers all the dots – make sure the ruler has the same downward slope as the data.
  • Now, turn the ruler on its side (thin edge of the ruler on the page).
  • Keeping the slope the same, move the ruler so that approximately half of the data points appear above the edge of the ruler and half are below it.
  • Now, draw a line along the edge of the ruler. This is a line of best fit! Continue reading Try this: Predicting reaction time
