Answer:

2 levels of the independent variable and 0 levels of dependent variable

Explanation:

Levels of independent variable indicate the types of experiment here. Here we have the control experiment and experimental group. The control experiment/group is the group that is not altered and used to measure the experimental group. The control group is the 50 children that took nutritious breakfast while the experimental group is the 50 children that took doughnuts /non nutritious food. If there are more than two types of experiment, the number of experiment types are the number of levels of the independent variable. The dependent variable here has 0 levels

Asch demonstrated that group unanimity exerted an influence on conformity, above group size alone.​ question 1 options: ​true. ​
Lorico [155]

The statement is TRUE.

In 1951 Solomon Asch carried out the famous Conformity Experiments, set out to <u>measure the dynamics of group-thinking</u>. He presented his subjects with an extremely simple judgement task with a very obvious answer, joined by a previously prepared group that was told to answer incorrectly on purpose. By making it so simple, it would be clear that any subject that answered incorrectly would be doing it because of group pressure. With this first experiment, <u>Asch proved a correlation between  a group's influence on an individual's conformity</u>.

Further trials went deeper into which factors were the most impactful to influence conformity. The results showed that <u>increasing group size</u> by up to three times, <u>raised the conformity levels to 32%</u>. However, larger groups did not impact this number. Applying group unanimity, on the other hand, showed an increase of as much as 80% on the conformity rates.

This clarified how much bigger of an influence unanimity was over group size, meaning it mattered more to an individual if an entire group agreed on something (even if the group was small), over a larger majority's opinion when a group was more split-up.


Hope this helps!
