He administersthe diagnostic interview to 28 children and records these scores. He thentrains an observer to independently rate anxiety-specific behaviors for each ofthe 28 children. These ratings are totaled for an overall “anxious behavior”score. On both the interview and the behavioral ratings, a higher scoreindicates higher levels of anxiety. These scores are listed in the table on thefollowing page. Conduct a Pearsoncorrelation coefficient analysis to determine whether there is a relationshipbetween the interview scores and the behavioral ratings for this group ofchildren.The steps will be the same as theones you have been practicing in Part 1 of the assignment—the only differenceis that you are now responsible for creating the data file as well. Remember toname and define your variables under the “Variable View,” then return to the“Data View” to enter the data.

(3 pts)3.  Writean APA-style Results section describing the outcome. All homework “Resultssections” must follow the example given in the Course Content document “WritingResults of Statistical Tests in Current APA Format” (Note: you do not have torefer to a figure). Be sure to include the direction of the relationshipbetween the variables (positive? negative? none?) in your section. (3 pts)4.  Aneuropsychologist is assessing the relationship between brain function andperformance on a visuo-spatial task. He administers a test to 14 patients onwhich scores can range from 1–20: a high score indicates normal brain function,and a low score indicates some levels of brain dysfunction. He then asks eachpatient to complete a maze and records the number of mistakes the patient makesfrom start to finish. The scores are listed in the table below. Conduct a Pearson correlation coefficientanalysis to determine what the relationship is, if any, between brain functionand performance on the maze task.The steps will be the same as theones you have been practicing in Part 1 of the assignment—the only differenceis that you are now responsible for creating the data file as well. Remember toname and define your variables under the “Variable View,” then return to the“Data View” to enter the data.

(3 pts)6.  Writean APA-style Results section describing the outcome. All homework “Resultssections” must follow the example given in the Course Content document “WritingResults of Statistical Tests in Current APA Format” (Note: you do not have torefer to a figure). (3 pts)7.  Thenull hypothesis for this scenario can be written as follows: “There is norelationship between level of brain function and the number of mistakes made ona maze task.” Based on your results, should this hypothesis be rejected orretained, and why? Write your answer in sentence form. (2 pts)Part 3: CumulativeHomework1.  Adevelopmental psychologist is studying whether students in a certain preschoolprogram perform better than preschoolers in the state in general on a measureof math readiness. The mean score for preschoolers in the state on the measureis 87. The psychologist tests the preschoolers in the program and records thescores in the table below. Choose the correct test to analyze this question,set up the SPSS file, and run the analysis. Follow the directions under thetable below.Math Readiness Scores908986917892887379898891938992a) Paste appropriate SPSS output. (2 pts)b) Paste appropriate SPSS graph. (2 pts)c) Write a Results section in current APA style describingthe outcome. All homework “Results sections” must follow the example given inthe Course Content document “Writing Results of Statistical Tests in Current APAFormat” (Note: you do not have to refer to a figure).
