SPSS Lab 2 Assignment -

This week, we continue using SPSS to perform statistical computations.

Aims of Lab - You will Revisit from Lab 1:

• Entering data by hand while Using "Variable View" & "Data View"
• Frequency Table; Central Tendency, Measures of Variability;
• Calculating Standardized Scores (Z-Scores);
• Creating a Bar Graph/Histogram with a normal curve;
• Deciding Significance and APA Final write-up;

Learn/Calculate for Lab 2:

• Calculating the One-Sample, Independent t-test, Dependent t-test, One-way ANOVA, Pearson-r Correlation, and the Chi-Square.

Lab Assignment 2 -

Given the follow random sample of GMAT test scores for senior college students in 2014, compute the following and answer the final questions in APA format.

1. First input the data into SPSS, you must ensure that all information is entered fully under variable view and all numbers are correct in data view, as well as run the appropriate descriptive statistics to answer the following questions. Make sure to save the output window in PDF format with all appropriate tables, graphs, and selected calculations/outputs for submission.

2. Enter the data set, create the appropriate charts in order to answer the following questions in APA format and complete sentences:

a. How many cases are there in the GMAT data set? That is, what is n?

b. What is the average GMAT test score for senior college students?

c. What are the highest and lowest score standard scores in the data set?

d. Given that the maximum GMAT score is 800, what percentage of senior college students scored above a 600?

e. Given that the national average GMAT score was 547 in 2014, what percentage of senior college students scored below the national average?

3. Select appropriate test to run, run it on SPSS, and then answer the following: Is there a statistically significant difference in the senior college students in comparison to the general population on the GMAT? Explain?

Given the following Key, download the data set and answer the following questions in APA format and complete sentences (i.e. ONLY step 4)?

acs_k3: average class size k - 3rd grade

acs_46: average class size 4 - 6th grade

meals: the percentage of students receiving free meals

full: the percentage of teachers that have full teaching credentials

api2000: academic performance of school in 2000

api1999: academic performance of school in 1999

enroll: number of students

mobility: percentage of students 1st year in school

emer: percentage of teachers that have emergency teaching credentials

yr_rnd: year-round school

ell: number of English Language Learners

mealcat: percentage of free meals in 3 categories (socioeconomic status of school)

qscore99 quiz scores for students for 1999          

4. Before you run data, you should first run basic descriptives to get familiar with the data. If you were to run descriptives for all variables being used in the study questions below, which would you calculate and/or run and why? (Central Tendency, Measures of Variability, Graphs, or Frequency tables) Explain which descriptives you would run for the variables utilized in the following questions and why? (THERE IS NOT DATA TO RUN HERE - this is about explanation, no SPSS output needed for this question).

5. Select appropriate test to run, run it on SPSS, and then answer the following: Is there a statistically significant difference in academic performance in 1999 between year-round and non-year-round schools? How do you know? Explain?

6. Select appropriate test to run, run it on SPSS, and then answer the following: Is there a statistically significant difference in academic performance from 1999 to academic performance in 2000? Explain?

7. Select appropriate test to run, run it on SPSS, and then answer the following: Is there a statistically significant difference in academic performance in 2000 according to the socioeconomic standing of the school as measured by the percentage of students that receive free meals? Explain.

8. Select appropriate test to run, run it on SPSS, and then answer the following: Determine if there is a significant relationship between academic performance in 2000 and the number of students.

9. Select appropriate test to run, run it on SPSS, and then answer the following: Determine if year-round status makes a difference in the socioeconomic status of the school.
