a researcher wanted to compare the final test scores of students who used two different types of study materials. the researcher randomly selected two samples of 20 students using each type of material and determined the final test score of each student. the table shows the mean final score and the mean absolute deviation (mad) for each sample.

the researcher can/cannot conclude that material 1 leads to higher final test scores because the distributions of the scores in the two samples are identical/somewhat similar/ similar/ different.

The researcher CAN

The two samples are DIFFERENT
