Psychologists rely on random assignment to assign subjects to different groups in an experiment.Random assignment leaves it completely up to chance to determine which subjects receive the critical part of the experiment, which is imperative for determining that the independent variable is indeed what creates the result.

Through random assignment, we ensure that other factors that may be contributing to reading speed, indicated here with the different colors for the subject.

For example, fluency or how often the subject reads for leisure, are represented equally in the two groups.

Therefore the study's results are generalizable to the population at large.

Random assignment occurs only in experimental settings where subjects are being assigned to various treatments.

Then you assign the subjects in your sample to two treatment groups.

One where they read some text in serif font and the other where they read the same text in Sans Serif font.

We call such variables con-founders or confounding variables.

In this setting, if we observe any difference between the average reading speeds of the two groups, we can actually attribute it to the actual treatment, the font type, and know that it its likely not due to the control confounding variable.

This allows us to attribute any observed difference between the treatment and control groups, to the treatment being imposed on the subjects since otherwise these groups are essentially the same.

In other words, random assignment allows us to make causal conclusions based on this study.
