Question

A researcher is interested in comparing an absenteeism-reducing program for high school students. He studies three schools: High School A, which uses the new absenteeism-reducing program, High School B, which uses the old program, and High School C, which does not use any program. Over 28 days, the number of students absent in those schools was recorded and represented in the table below: High School A 1 2 2 1 3 1 2 1 3 2 2 4 0 4 4 1 2 3 2 1 2 4 2 5 5 3 7 4 4 6 High School B 2 5 7 3 6 6 6 2 5 4 3 7 1 2 2 1 3 1 2 1 3 2 2 4 0 4 4 1 2 3 High School C 2 1 2 4 2 5 5 3 7 4 4 6 2 5 7 3 6 6 6 2 5 4 3 7 Enter your data into SPSS, then run a one-way ANOVA and answer the questions: 1) State the independent variable and dependent variable. 2) Check the assumptions of ANOVA and determine if the data satisfy those assumptions to conduct ANOVA. (This includes normality tests, histogram, and skewness kurtosis) 3) Show the ANOVA summary table and report the findings of ANOVA. Thanks in advance!

Enter your data into SPSS, then run a one-way ANOVA and answer the questions:

1) State the independent variable and dependent variable.
2) Check the assumptions of ANOVA and determine if the data satisfy those assumptions to conduct ANOVA. (This includes normality tests, histogram, and skewness kurtosis)
3) Show the ANOVA summary table and report the findings of ANOVA.

Thanks in advance!

00:01 Hi, i'm david and i'm here to help you answer your question.

00:03 Now let me bring up your question here.

00:06 In the question here, we are given the data set for the high school ap and c.

00:11 And we need to pass the data into the spss to run the anova table.

00:17 And in the first one, asking to stain the independent variable and dependent variable.

00:23 So we have the independent variable that will be the type of the school.

00:29 And it has the three levels a, b and c.

00:48 And we'll have the dependent variable.

00:56 That will be, this will be the number of the student absence.

01:01 So the number of students absence.

01:14 And then that's going to be the question one.

01:17 For the question two, we will need to change the assumption on the anovar.

01:21 So when we pass the data into the calculator, the first one will have to make sure that the three symbols are random and independent.

01:42 And the second assumption that will be three population are normally distributed.

02:00 And the next one will be the assumption that they have equal variance.

02:11 And the equivalents here can be verified when we compute the s -1 we get equal to 1 .7 -043 when the s -2 equal to the 1 .4 -3 -28 and the s -3 equal to 1 .98 77.

02:33 So they are quite close to each other.

02:36 And that will be the question 2...
