Question
Some researchers were concerned with college students' confidence to handle dangerous "social" situations. One of their investigations compared Freshman through Senior students on a measure of confidence to handle so-called social danger (such as getting lost late at night in a strange city, being approached by a enacing stranger when out alone, losing your car keys alone at night, etc.) The confidence measure is shown below: Rate how confident you are to successfully handle a dangerous social situation: Not at all Slightly Somewhat Quite Extremely 2 Some findings of the comparison of classification groups are now given: 218 238 200 199 855 3.22 3.41 Freshman 2 Sophomore Junior Senior Total 75 81 73 73 76 3.34 Sum of Mean DE Square Source Between Within Total uaresS 2.80 489.12 851 493.94854 0.57 fishers tSt Post-hoc and effect size analyses [Note: t (DF) 1.65] LSD MeanS 3.22 3.41 Difference Freshman vs Sophomore Freshman vs Junior -0.19 3.22 3.33 -0.11 Freshman vs Senior3.22 3.39-0.17 Sophomore vs Junior3.413.330.08 0.02 Junior vs Senior 3.33 3.39 -0.06 0.23 -1.48 -0.15 -2.29 -0.23 1.10 0.11 0.27 0.03 -0.79 -0.08 Sophomore vs Senior3.41 3.39 study the infrmation above; when ready, write answers to the four tasks on the reverse side of this pageExplanation / Answer
Case 1
Ho : College students are not significantly confident in their ability to handle dangerous social situations.
H1 : College students are significantly confident in their ability to handle dangerous social situations.
Case 2
Ho : Freshmen are not significantly more confident in their ability to handle dangerous social situations, versus the same confidence in seniors.
H1 : Freshmen are significantly more confident in their ability to handle dangerous social situations, versus the same confidence in seniors.
Next:
It is not necessary to test the assumption of homogenous variance in this case, because large samples are taken in each of the cases.
