Question

3) Ms. Phillips is a kindergarten teacher whose class is always high energy after lunchtime. Ms. Phillips has a theory that perhaps recess should be longer, allowing her students to tire themselves out and be better able to focus after lunch. She records the number of minutes each student takes to calm down after lunch time with their original 20 minute recess (time 1) and after the new extended recess of 45 minutes (time 2). Is a longer recess time effective in Student 1 20 minute recess (Time 1) 19 20 2 3 45 minute recess (Time 2) 2 7 14 13 3 4 5 13 24 18 19 23 20 6 7 8 + 10 16 9 4 17 10 8 16 a. What is the independent variable? 9 b. What is the dependent variable? C. What test did you use to analyze the data? d. Is the test significant? How do you know? e. Write the statistical notation in APA style f. Report the findings in 1-3 sentences. Make sure to include the independent variable, the dependent variable, all relevant statistics and a summary
please answer the questions also any way for a creation of a graph including SEM bars to display the results? if not- its okay! just need questions answered! ill give thumps up! thanks

Answer 1

1) Independent Variable : Recess timing

Independent variable is the varible controlled or changed by the experimenter and is the cause for the dependent variable.

Here, Recess timing is changed by the experimenter.

2) Dependent variable : Time taken by the students to calm down.

change in recess timing causes change in time in calming down. that is; variation in independent varible causes change in dependent variable.

3) Measuring central tendencies can be used to analyse the data to find the difference in forst and second condition.

4)Yes, it is significant. Because in the experiments wherein the goal is to find out the difference, meansuring by using central tendencies is helpful to analyse data.
