Question

The median for the samples from the school math contest are:
The median of Sample 1 from Grades 9 and 10 is 79.
The median of Sample 2 from Grades 11 and 12 is 86.
What conclusions can you derive from the random samples?

The students performed equally between all the grades.

The students in grades 11 and 12 scored higher than the students in grades 9 and 10.

The students in grades 11 and 12 are likely to do well in college.

The students in grades 9 and 10 were not allowed enough time in the school math contest.

The sample size was too small to derive a valid conclusion

Answer 1

A conclusion which can be derived from these random samples is that: B. the students in grades 11 and 12 scored higher than the students in grades 9 and 10.

What is a median?

A median can be defined as the middle number (center) of a sorted data set, which is when the data set is arranged in from the greatest to least or the least to greatest.

In Mathematics, the median of a data set is generally considered to be a better measure of center than the mean when there's an outlier in the data set.

Based on the information provided for these samples, we can logically conclude that the students in grades 11 and 12 scored higher than the students in grades 9 and 10 because a median score of 86 is greater than a median score of 79.
