PART A: FITTS LAW (use file: Fitts Law MT_Index of Difficulty.sav)
1. Perform a linear regression analysis to determine how Index of Difficulty
(independent)
and speed (MT) are related. Observe the correlation coefficient, R 2, and the
regression line equation.
, 2. Create a scatter plot displaying Index of Difficulty (x-axis) and MT (y-axis). Add the
regression line in the plot.
PART B: SEX differences (use file: Fitts Law MT_VE_SEX_HAND.sav)
1. Perform a linear regression analysis to determine how Index of Difficulty
(independent) and speed (MT) are related. Observe the correlation
coefficient, R2, and the regression line equation.
