In this experiment, participants were asked to fire five paintballs at a target at 10, 20 and 30 m, and accuracy and shooting time was recorded. Accuracy was determined by measuring the distance from the centre of the paintball mark to the centre of the target. Speed was measured as the time between the first and last shot being fired.   It is hypothesized that accuracywill be the greatest  and shooting time will be the least comparable  at 10 m from the target. 10, 20 and 30 m, i.e. irrespective of distance.  The contrary null hypothesis is that the greatest  accuracy and fastest  shooting time will be equal for 10, 20 and 30 metre shooting distances. at 10 m from the target.  The largest covariate that affects results is the experience of the participants. It is expected that the category of experienced participants will have a faster mean shooting time, and also have a greater mean accuracy. Experience is defined here as having used a paintball marker before. As such, the effect of experience on accuracy and shooting time shall be discussed later in this report.
