The ideal sample size is calculated by using the following formula:

(Z-score)2 x SD x (1-SD)/ME2 = Sample Size

Thus, small sample size which is 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.

Out of the numerous feasible mistakes, the random mistakes cannot be decided inside the everyday method of measurement. Such errors are treated mathematically. The mathematical analysis of the numerous measurements is called statistical evaluation of the statistics.

The misinformation effect illustrates that our __________ can be influenced by ____________. group of answer choices
kotykmax [81]

The misinformation effect illustrates that our minds can be influenced by a misconception.

Inaccurate or deceptive information is called misinformation. It differs from disinformation, which is blatantly false information. Rumors are unreliable and frequently unverified information that cannot be proven to be true or false. They are information that is not attributed to a specific source. The misinformation effect occurs when post-event information causes a person's recall of episodic memories to be less accurate. Since the middle of the 1970s, the misinformation effect has been researched. The tendency for information received after an event to obstruct one's memory of the original events is known as the "misinformation effect." According to research, even relatively subtle new information introduced later can have a significant impact on how people recall past experiences.
