An experiment was conducted to examine the performance (as measured by the number of errors made) on a motor skills task. Twenty-four subjects (12 young and 12 old) were assigned to either an easy or hard motor skills task. There were two factors in the study: age (young/old) and difficulty of the motor skills task (easy/hard). The number of errors made on the motor skills task was recorded for each person and is presented in the table below. Null and Alternative Hypotheses: H0: There is not an interaction b
An experiment was conducted to examine the performance (as measured by the number of errors made) on a motor skills task. Twenty-four subjects (12 young and 12 old) were assigned to either an easy or hard motor skills task. There were two factors in the study: age (young/old) and difficulty of the motor skills task (easy/hard). The number of errors made on the motor skills task was recorded for each person and is presented in the table below.
Null and Alternative Hypotheses:
H0: There is not an interaction between young and old
H0: µYoung = µOld
H1: There is an interaction between young and old
H1: µYoung ≠ µOld
H0: There is not an interaction between easy and hard
H0: µEasy = µHard
H1: There is an interaction between young and old
H1: µEasy ≠ µHard
H0: There is not an interaction between age and difficulty
H0: µAge = µDifficulty
H1: There is an interaction between age and difficulty.
H1: µAge ≠ µDifficulty
I need the partial η2 scores for this, they are all bellow
F(1, 20) = 21.16, p (= 0.00017) < 0.05, partial η 2 = ?
Young (M = 5.92, SD = 2.23) Old (M = 9.5, SD = 4.21)
F(1, 20) = 42.57, p (= 0.000002) < 0.05, partial η 2 = ?
Easy (M = 5.17 SD = 1.95) Hard (M = 10.25, SD = 3.44)
F(1, 20) = F(1, 20) = 6.05, p (= 0.0231) < 0.05, p ?, partial η 2 = ?
