Question

To study the effects of early experience on conditioning, and experiment raised four groups of rats (randomly assigned) in the presence of (1) no special stimulus (2) a tone stimulus (3) a vibratory stimulus and (4) both a tone and vibratory stimulus. The rats were later classically conditioned (at random) using one of three intervals to foot shock as the unconditional stimulus. The dependent variable was the number of trials to reach learning (a predetermined number of trials).

a) describe the type of ANOVA used to analyze the data

b) what are the independent variables? How many levels do each have?

c) what is the dependent variable?

d) check assumptions

e) what are the three sets of hypotheses?

Answer #1

A) Type of ANOVA used here is Two way ANOVA.

b) Experience on conditioning and Unconditional stimulus.

Experience on conditioning has FOUR levels

and Unconditional stimulus has THREE levels

c) The dependent variable is the number of trials to reach learning (a predetermined number of trials).

d) Assumptions: HOMOGENEITY OF VARIANCE

NORMALITY OF DATA.

d) NULL HYPOTHESIS H0:

ALTERNATIVE HYPOTHESIS Ha: At least one mean is different .

NULL HYPOTHESIS H0:

ALTERNATIVE HYPOTHESIS Ha: At least one mean is different.

Null hypothesis H0: Conditioning Experience and Unconditional stimulus are independent of each other .

Alternative Hypothesis Ha: Conditioning Experience and Unconditional stimulus are NOT independent of each other .

NOTE: Data are not available so cant check the assumptions.
