    Question

    A researcher relates the number of hours spent practising and the ability to successfully execute a specific skill (e.g. diving, arm stand dive, high board dive) with the use of a linear regression model: the more you practise, the better the performance of the dive.

    Calculate the predicted score in a diving competition if they have amassed 250 hours of training. Assume that the slope of hours of training = .1016 on diving performance and the constant = 22.5 in the regression equation. Use only one decimal!


    Solution

    The regression equation is: Diving score = 22.5 + 0.1016*hours training
     If you replace hours with 250: (diving score = 22.5 + 0.1016 * 250), you will reach the outcome 47.9
