In Example 2, the scores within each group are very close together, but the groups are very different from one another. Because between-group variation is large and within-group variation is small, the video concludes that the type of drink makes a big difference, leading to rejecting the null hypothesis.
Conditions: The displayed Example 2 data are used.; Between-group variation is much larger than within-group variation.

Total variation in the observed scores is split into two parts: within-group variation, which is caused by differences among individuals inside the same group, and between-group variation, which is associated with differences among the groups themselves.
Conditions: The data are organized into multiple groups.; One is analyzing variation in a measured response across those groups.
