One group of 50 students took a distance learning class, while another group of 25 took the same course in a traditional face-to-face classroom. Both group were given the same mid-term test. The average score of the distance learning group was 54.6 with a standard deviation of 12.4. The average score for the group who took the course in the traditional format was 60.6 with a standard deviation of 14.5. At a significance level of 0.1, can it be concluded that there is a difference in average score of students between the distance learning and face-to face instruction formats? What is your decision? Enter “R” if your decision is to reject the null hypotheses. Enter “F” if the decision is do not/fail to reject the null hypotheses. Your answer (R/F) is: Using a significance level of 0.1, which of the followings is/are an appropriate/correct statement regarding the difference in students score under the two different instructional modes. Enter “A” if the statement is appropriate/correct and enter “N” if the statement is not appropriate/correct. The data supports that the students’ average score is different between the two instructional formats. Your answer(A/N) is: The data does not support that the students’ average score is different between the two instructional formats. Your answer (A/N) is: The data supports that the student’s average score is higher under face-to-face format than the distance learning. Your answer (A/N) is:

Question

One group of 50 students took a distance learning class, while another group of 25 took the same course in a traditional face-to-face classroom. Both group were given the same mid-term test. The average score of the distance learning group was 54.6 with a standard deviation of 12.4. The average score for the group who took the course in the traditional format was 60.6 with a standard deviation of 14.5. At a significance level of 0.1, can it be concluded that there is a difference in average score of students between the distance learning and face-to face instruction formats?

What is your decision?

Enter “R” if your decision is to reject the null hypotheses. Enter “F” if the decision is do not/fail to reject the null hypotheses.

Your answer (R/F) is:

Using a significance level of 0.1, which of the followings is/are an appropriate/correct statement regarding the difference in students score under the two different instructional modes.

Enter “A” if the statement is appropriate/correct and enter “N” if the statement is not appropriate/correct.

The data supports that the students’ average score is different between the two instructional formats. Your answer(A/N) is:

The data does not support that the students’ average score is different between the two instructional formats. Your answer (A/N) is:

The data supports that the student’s average score is higher under face-to-face format than the distance learning. Your answer (A/N) is:

Definition Definition Measure of central tendency that is the value that occurs most frequently in a data set. A data set may have more than one mode if multiple categories repeat an equal number of times. For example, in a data set with five item—3, 5, 5, 29, 473—the mode is 5 because it occurs twice and no other value occurs more than once. On a histogram or bar chart, the element with the highest bar represents the mode. Therefore, the mode is sometimes considered the most popular option. The mode is useful for nominal or categorical data (e.g., the most common color car that users purchase), but it is problematic for continuous data because it is more likely not to have any value that is more frequent than the other.
