HO 1: Reward results produce better exam results than either punishment or indifference.

HO 1: Reward results do not produce better exam results than either punishment or indifference.

HO 2: Indifference will lead to significantly better exam results than punishments.

HO 2: Indifference will not lead to significantly better exam results than punishments.

From the above descriptive statistics, it can be observed that the mean, standard error and standard deviation are the important values, which presents the key aspects of the data. In this context, it is noted that for each experimental condition, total sample size of 10 is selected. The mean values of punish, indifference and reward are 50, 56 and 65 respectively. However, among the variables under consideration that are punishment, indifference and reward, it is noted that there is too much deviation in the indifference as compared to other two variables.

From the given analysis of variance table, it is reflected that the value is under 0.05, presenting statistical significance. Keeping this in view, it can be said that there is statistically significant difference of teaching style on exam marks. Though, it does not clarify that what sort of effect exist for teaching style.

As there are particular hypotheses, some contrasts are specified. The above table of contrast coefficients indicates the codes which are used. The first contrast compares indifference and punishment which are both coded with 1 against reward which is coded with -2. On the other hand, second contrast compares indifference which is coded with -1 in opposition to punishment which is coded with 1. It is important to consider that the codes for each contrast equal to zero, and that in contrast ...
