Question;SPSS Homework 5 Instructions;Correlation;Part;1;Green;Salkind: Lesson 31, Exercises 1?4;The following helpful tips are numbered to;correspond with the exercise number to which they refer (a dash indicates that;no tips are needed);1.;---------- (2 pts for output;and 2 pts each for a?c);2.;Answer this question in;sentence form. Include the correlation (r) and degrees of freedom, the p value;and whether these values indicate a significant correlation between the;variables or not. (2 pts);3.;All homework ?Results sections?;must follow the example given in the Course Content document ?Writing Results;of Statistical Tests in Current APA Format? (Note: you do not have to refer to;a figure). (2 pts);4.;---------- (2 pts);Part;2;1. A clinical psychologist would like to determine whether there is a;relationship between observer ratings of children?s anxious behaviors and;scores on an established diagnostic interview assessing anxiety disorders. He;administers the diagnostic interview to 28 children and records these scores.;He then trains an observer to independently rate anxiety-specific behaviors for;each of the 28 children. These ratings are totaled for an overall ?anxious;behavior? score. On both the interview and the behavioral ratings, a higher;score indicates higher levels of anxiety. These scores are listed in the table on;the following page. Conduct a Pearson;correlation coefficient analysis to determine whether there is a relationship;between the interview scores and the behavioral ratings for this group of;children.;The steps will;be the same as the ones you have been practicing in Part 1 of the assignment?the;only difference is that you are now responsible for creating the data file as;well. Remember to name and define your variables under the ?Variable View,?;then return to the ?Data View? to enter the data. (3 pts);Interview (Range 0?9);Anxious Behavior Rating;(Range 0?25);3;7;2;6;4;6;9;21;7;20;7;18;4;10;8;9;3;5;3;7;2;5;1;3;6;17;8;19;8;23;7;22;1;4;2;7;3;7;3;3;5;13;8;20;7;16;4;12;6;13;6;18;5;15;2;9;2. Create a simple;scatterplot of the relationship between these variables (define interview;scores as the x-axis and behavioral ratings as the y-axis). (3 pts);3. Write an APA-style Results section describing the outcome. All;homework ?Results sections? must follow the example given in the Course Content;document ?Writing Results of Statistical Tests in Current APA Format? (Note;you do not have to refer to a figure). Be sure to include the direction of the;relationship between the variables (positive? negative? none?) in your section.;(3 pts);4. A neuropsychologist is assessing the relationship between brain;function and performance on a visuo-spatial task. He administers a test to 14;patients on which 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 each patient to complete a maze and records the number of mistakes;the patient makes from start to finish. The scores are listed in the table;below. Conduct a Pearson correlation;coefficient analysis to determine what the relationship is, if any, between;brain function and performance on the maze task.;The steps will be;the same as the ones you have been practicing in Part 1 of the assignment?the;only difference is that you are now responsible for creating the data file as;well. Remember to name and define your variables under the ?Variable View,?;then return to the ?Data View? to enter the data. (3 pts);Dysfunction Score;Number of Mistakes on;Maze Task;3;25;8;18;9;18;4;26;15;6;6;19;18;3;17;4;19;6;6;16;5;14;20;2;17;5;5;23;5. Create a simple scatterplot of the relationship between these;variables. (3 pts);6. Write an APA-style Results section describing the outcome. All;homework ?Results sections? must follow the example given in the Course Content;document ?Writing Results of Statistical Tests in Current APA Format? (Note;you do not have to refer to a figure). (3 pts);7. The null hypothesis for this scenario can be written as follows;?There is no relationship between level of brain function and the number of;mistakes made on a maze task.? Based on your results, should this hypothesis be;rejected or retained, and why? Write your answer in sentence form. (2 pts);Part;3: Cumulative Homework;1. A developmental psychologist is studying whether students in a;certain preschool program perform better than preschoolers in the state in;general on a measure of math readiness. The mean score for preschoolers in the;state on the measure is 87. The psychologist tests the preschoolers in the;program and records the scores 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 the table below.;Math Readiness Scores;90;89;86;91;78;92;88;73;79;89;88;91;93;89;92;a);Paste appropriate SPSS output.;(2 pts);b);Paste appropriate SPSS graph.;(2 pts);c);Write a Results section in;current APA style describing the outcome. All homework ?Results sections? must;follow the example given in the Course Content document ?Writing Results of;Statistical Tests in Current APA Format? (Note: you do not have to refer to a;figure). (2 pts);Submit this assignment by 11:59 p.m. (ET);on Monday of Module/Week 5.
