Standard deviation is a mathematical tool to help us assess

• experimenter bias

What is meant by participant variable?

Reliability refers to the

• precise way of measuring what it is supposed to measure.

• accuracy of a measure (whether the results really do represent what they are supposed to measure).

• consistency of a measure (whether the results can be reproduced under the same conditions).

• measures: if the results of a given study are accurate, true for different kinds of people and relevant to the real world.

Standardisation refers to the

• process to adhere to human ethics.

• process in which procedures used in research are kept the same.

• experimenter bias.

• great attention is taken to keep all elements of a procedure identical.

Controlled experiments require:
