  1. Does SiZe Matter? An analysis of Orientation Group Size and Cumulative GPA

  2. Description: Three Freshman Orientation Groups of different size Group #1 Less than 10 students/group Total:6 groups Group #2 10 – 20 students/group Total:6 groups Group #3 More than 20 students/group Total:6 groups Total Sample Size: 264

  3. Description Extras: Total Sample Size: 264 Gender:Males 139Females 125 Ethnicity: Age:17 – 72 yearsAve = 24 years

  4. Variables: Dependent Variable:Cumulative GPA(Entering Students with GPA a 0 so the CUM GPA = Semester GPA) Independent Variables: Course Section/Group GenderAgeEthnicity

  5. Hypothesis: Research Question: Does attendance in a smaller size (n = < 10) students result in a higher GPA after the first semester? H0:µgroup1 = µgroup2 = µgroup3 There is no difference between the cumulative GPA of students in relation to their group size. Ha: µgroup1 ≠ µgroup2 ≠ µgroup3 There is a difference between group size in relation to cumulative GPA.

  6. ANOVA: No significance was found between group size and cumulative GPA, F(2, 261) = 1.054 p = .350 Mean GPA for all three groups: Group 1: N = 38 GPA = 2.53 Group 2: N = 90 GPA = 2.73 Group 3: N = 136 GPA = 2.82

  7. CORRELATION: A positive, but not significant, relationship existed between Cumulative GPA and Group Size, R = .086. Mean GPA for all three groups: Group 1: N = 38 GPA = 2.53 Group 2: N = 90 GPA = 2.73 Group 3: N = 136 GPA = 2.82

  8. REGRESSION: • Group Size did not account for a difference in GPA, R2 = .007, F(1, 261) = 1.961, p= .163 • Genderdid account for a difference in GPA,R2 = .036, F(1, 261) = 7.690, p= .006 • Age did no account for a difference in GPAR2 = .044, F(1, 261) = 2.252, p= .135 • Ethnicity did not account for a difference in GPAR2 = .007, F(1, 261) = 1.961, p= .163

  9. GENDER ANAYLSIS: Significance was found between group size and cumulative GPA, F(2, 261) = 7.957 p = .005 • Female students displayed higher GPAs than male students, regardless of group size. Female GPA: 2.95Male GPA: 2.57

  10. RESULTS: • Failed to reject the Null Hypothesis • Significance found for GENDER and GPA • Ethnicity limitation due to small samples of minority populations. • Separate study including all sections (N = 450) produced similar results (even a large size did not matter. SIZE DOES NOT MATTER!

  11. DIRECTION: • Need to look at group attrition from matriculation to orientation course completion (drop outs have lower GPAs? • Conduct a study with group sizes > 30 for different results. • Controls for High School GPA and ACT as mitigating factors for self-selection and higher first semester GPA, regardless of orientation or orientation class size. • Replicate study = different results? Triangulate the data with literature, additional studies, etc.
