svetlana [45]
Question is which is NOT a good technique.
Answer is "B" and here's why:

A) Clear questions -- good. People understanding the question will answer accurately.
C) Large sample size -- good. Answers will be more accurate with more people asked (like if you flip a coin 1,000 times its going to be closer to 50% heads than if you only flipped it twice)
D) Random sample -- good. Avoids your own bias in choosing who to ask.

B) Push poll -- bad. Pretends to be unbiased, the pollster's real objective is to get a person thinking in a way that is to their advantage. Some political candidates do this just before elections.

Zarrin [17]

Answer:

EXERCISE

Explanation:

In an experiment, the independent variable is the variable that the experimenter changes or manipulates in order to bring about a measurable outcome.

In this case, an experiment is carried out to test the hypothesis that "exercise will affect the number of times a person can squeeze a clothespin in a certain amount of time". The experiment contained two groups (one group sits quietly before squeezing a clothespin as many times as possible and the other does 25 JUMPING JACKS before squeezing a clothespin as many times as possible).

The independent variable is the EXERCISE (jumping jacks) that was changed for each group in the experiment.
