Science Fair Attitude Questions (12 possible points):
Item 1: I enjoyed competing in the science fair: 4 = strongly agree, 3 = agree, 2 = disagree, 1 = strongly disagree
Item 2: The science fair was exciting: 4 = strongly agree, 3 = agree, 2 = disagree, 1 = strongly disagree

Explanation / Answer
Result:
oe collected a questionnaire from 28 students in his school on their attitudes toward the local science fair. Joe wanted to test the following null hypothesis:
H01: There is no significant difference among the attitude toward science fairs of students’ who either won 1st, 2nd, 3rd, or no award at all at the local science fair.
See questionnaire sheet below:
Award Question:
What award did you win? (1 = 1st place, 2 = 2nd place, 3 = 3rd place, 4 = I did not win an award)
Science Fair Attitude Questions (12 possible points):
Item 1: I enjoyed competing in the science fair: 4 = strongly agree, 3 = agree, 2 = disagree, 1 = strongly disagree
Item 2: The science fair was exciting: 4 = strongly agree, 3 = agree, 2 = disagree, 1 = strongly disagree
Item 3: The science fair was fun: 4 = strongly agree, 3 = agree, 2 = disagree, 1 = strongly disagree
Data Collection Sheet: (Note: See the data collection sheet below. You may cut and paste or type the data set into SPSS. Remember to leave off the header row when copying into SPSS).
ANOVA
H_0: mu_1 = mu_2= mu_3 = mu_4
H1: At least one pair of population means are different
Calculated F=41.677, P=0.0000 which is < 0.05 level of significance. Ho is rejected.
We conclude that there is significant difference among the attitude toward science fairs of students’ who either won 1st, 2nd, 3rd, or no award at all at the local science fair.
Post hoc test shows that group 4 is significantly different from Groups 1,2 and 3.
Between Groups 1,2 and 3 , there is no significant differences.
