Research Methods & Analysis in Psychology.

Researchers compared two groups of 15 children on the time taken, in weeks, to learn how to ride a bicycle. The first group of children were shown a video of children cycling and then expected to learn without adult assistance. The second group were taken out by their parents who ran beside them and let go of the bicycle for increasingly longer periods until the child had learned. The researchers hypothesised that the second method would produce faster learning.

Prior to analysis the data were screened to ensure that they met the requirements for a parametric test. As the data met the requirements, an independent samples t-test was used to compare the mean reading scores obtained for children taught by formal and self-paced methods.
