In a study of the relation between happiness and personality, researchers combined the results of over 100 studies to conclude that people who are highly social and do not worry much are happiest. This study is best described as a(n):

Dr. Bloomin wants to investigate the impact of talking to plants on their growth. He decides to talk to a group of 40 tulips each day for six weeks. A second group is not talked to at all. After six weeks he discovers that the tulips he talked to are five centimetres taller than the tulips not talked to. In this example, the independent variable is:

The psychologist Robert Rosenthal told student researchers that some rats in a study would learn a task quickly and others would learn the task slowly. In reality, there was no difference in the rats' ability to learn the task. When the students tested the rats, the animals' learning matched what the students were told. These results reflect:

When a researcher's bias affects the coding of data, there is a problem with:

Jafar conducted an experiment with student participants in which he investigated their reactions to advertisements that used humour. When analyzing his results, he should take into account that:

The statistic that involves the basic arithmetic average of a set of scores is known as the:

George is looking for a research project. He could make use of theory because:

One criticism that is made of many experimental studies in psychology is that:

Stanley Milgram's obedience studies in which participants thought they were delivering electrical shocks to another person have been criticized on ethical grounds because:

If a researcher applies scalp electrodes to get measurements of brain activity, the researcher is using:

If you list a set of scores from the lowest value to the highest, then take the middle value to indicate what is a typical score, you are using the:

The most frequently occurring score in a data set is known as the:

Something is considered a variable if it:

You are interested in studying a condition, called Coltard's syndrome, where people think that they are actually dead. Because this condition is very rare, you can only find one person to study. The technique you are most likely to use is:

When researchers collect enough data to develop an explanation of why people behave as they do, the researchers are creating a(n):

An extensive study of a single person or a few people is characteristic of:
