Question
Fitts' law Fitts's law (often cited as Fitts' law) is a predictive model of human movement primarily used in human-computer interaction and ergonomics. This scientific law predicts that the time required to rapidly move to a target area is a function of the ratio between the distance to the target and the width of the target[1]. Fitts's law is used to model the act of pointing, either by physically touching an object with a hand.
The metric combines a task's index of difficulty (ID) with the movement time (MT, in seconds) in selecting the target. In Fitts's words, "The average rate of information generated by a series of movements is the average information per movement divided by the time per movement.
the is a figure of fitts' law experiment.
a.write 1 paragraph (>3 sentences) discussing the interpretation of the slope.

From the given graph of linear fit, it is clearly seen that the model is not fitted.
i.e.predicted data is not significant with the sample data.
We can say that, Y is dependent on X.
Average time to complete movement is based on the target size(bits).
Experimental data is too much deviating from the model.
Standard deviation is high.
Thank you.
