Final answer:
Differences in means refer to the comparison of the means of two or more populations or groups in statistics.
Step-by-step explanation:
In statistics, differences in means refer to the comparison of the means of two or more populations or groups. This comparison allows us to determine if there is a significant difference between the average values of the groups being compared.
For example, if we have two samples of students, one receiving a certain teaching method and the other receiving a different method, we can compare the means of their test scores to see if there is a significant difference between the two methods.
By calculating the differences in means and performing statistical tests, we can make conclusions about the significance of the observed differences and draw insights from the data.
