Question;SPSS ASSIGNMENT #7Analysis of VarianceSPSS instructions:Open SPSSAnalyze the data for #1. Remember that SPSS assumes that all the scores in a row arefrom the same participant. In this study, there are 15 participants divided into threegroups of five. Therefore, each of the 15 participants will be described by two variables,type of therapy and the number of activities of daily living performed.If ?1? represents the group receiving individual therapy for 1 hour every 2 weeks, ?2?represents the group receiving 1 hour of individual therapy each week, and ?3? indicatesthe group receiving 2 hours of individual therapy each week, the first participant will bedescribed by entering ?1? in the top cell of the first column in the Data View window and?16? in the top cell of the second column to indicate that the participant underwent 1hour of therapy every 2 weeks and performed 16 activities of daily living. The secondparticipant will be described by ?1? and ?15?, and the third by ?1? and ?18?.When the two variables have been entered for the five participants in this group, repeatthe process for participants who underwent 1 hour of individual therapy each week,using ?2? to describe their therapy group. When the two variables for the fiveparticipants in this group have been entered, repeat the process for Group 3, entering?3? in the first column. In the Variable View window, change the first variable name to?THERAPY? and the second to ?ADL? and set the decimals for both to zero.Click Analyze? Compare Means? One?Way ANOVA?Since ?THERAPY? is alreadyselected, you can click the arrow to move the variable to the Factor window. Select?ADL? and click the arrow to move the variable to the Dependent List window, whichinstruct SPSS to conduct the analysis of variance on the number of activities performed.1.Keep in mind that the clients in Group 1 will receive 1 hour of therapy every 2weeks, the clients in Group 2 will receive 1 hour of therapy every week, and theclients in Group 3 will receive 2 hours of therapy every week.Use the five steps of hypothesis testing to determine whether the observeddifferences in the number of activities in the following table performed by thethree groups are statistically significant at the.05 level of significance. Clearlyindicate each of the five steps.Calculate the effect size for the study. Explain your results.CLIENT123452.GROUP 11518162119GROUP 21919172320GROUP 32421222022A researcher interested in the relationship between student perception of theprobability of success in a statistics course and student motivation hasadministered an inventory designed to assess motivation in 18 students.The students have been divided into groups as follows: Students in Group 1believe they are highly likely to succeed in the course, students in Group 2believe they have an intermediate probability of success, and students in Group3 believe they have little chance of success.Use the five steps of hypothesis testing to determine whether the observeddifferences in level of motivation in the following table are statistically significantat the.05 level of significance. Clearly indicate each of the five steps.Calculate the effect size for the study. Explain the results of the hypothesis?testing procedure to someone who is familiar with the t test for independentmeans, but not with analysis of variance.SUBJECT1234563.GROUP 1(HIGH)9.08.56.57.08.05.5GROUP 2(INTERMEDIATE)3.55.53.53.56.57.0GROUP 3(LOW)8.05.56.54.55.56.0Due to the increasing number of trails involving testimony by behavioralscientists, a professional organization of behavior scientists asked judges,attorneys, jurors, and law enforcement officials to use a 10?point scale to rate theeffect of such testimony on trial outcomes.The results are presented in the table below. Use the five steps of hypothesistesting to determine whether the observed differences in effectiveness ratingsare statistically significant at the.01 level of significance. Clearly indicate each ofthe five steps.Calculate the effect size for the study.
