Answer:

A double-blind study is one in which neither the participants nor the experimenters know who is receiving a particular treatment. This procedure is utilized to prevent bias in research results. Double-blind studies are particularly useful for preventing bias due to demand characteristics or the placebo effect.

For example, let's imagine that researchers are investigating the effects of a new drug. In a double-blind study, the researchers who interact with the participants would not know who was receiving the actual drug and who was receiving a placebo.

ella [17]

Answer:

(1).Online audiences have more sources of distraction than do in-person audiences.

(2). Online speakers should dress casually because the audience is not physically present.

Explanation:

PLEASE TAKE NOTE:

For option (1) that is ''Online audiences have more sources of distraction than do in-person audiences". THIS IS THE (ONLY) ANSWER IF WE ARE TO CHOOSE ONLY ONE OPTION.

BUT if we are to choose more than one answers OPTION (1) AND (2) ARE THE BEST TWO ANSWERS TO THE QUESTION.

REASON:

(1).Online audiences have more sources of distraction than do in-person audiences: It is so easy for the Audience to get distracted by their phones or people knocking on their doors and many more. It is not easy to keep decorum.

(2). Online speakers should dress casually because the audience is not physically present : it is okay if an online speaker dresses casually but it will better if an online speaker dresses professionally as the audience will take them more seriously.

=> So, like I said earlier; if we are to choose only one option, the best option you have to choose is "Online audiences have more sources of distraction than do in-person audiences".

In general, the information Alex gave is credible because it is a girl who stole a candy bar, but some part of the information is false, that part of the information that appears as a gap in memory for various reasons. These gaps in memory can occur as a result of the excitement or authority of a police uniform, and are usually filled with false information as a product of suggestibility.
