The two reasons why they are not appropriate to try to perform statistical evaluations are 1.) Reduces the confidence level of the study, which is related to the Z-score. 2.) Decreasing the sample size also increases the margin of error.
The ideal sample size is calculated by using the following formula:
(Z-score)2 x SD x (1-SD)/ME2 = Sample Size
Thus, the small sample size which in this case very small (9 or less)
1. Reduces the confidence level of the study, which is related to the Z-score.
2. Decreasing the sample size also increases the margin of error.
Thus, these 2 reasons state why it is not appropriate to use statistical evaluation on the data obtained from task-based protocol and has a very small sample size.
Evaluation involves attributing a significant value to the statistics that are collected. As expected, evaluation denotes putting a “cost” at the obtained measurement. The values can be compared to a reference population (i.e., are “norm-referenced”) or to some type of standard (i.e., are “criterion-referenced”).
