Stacey Finkelstein and Ayelet Fishbach (2012) examined the impact of feedback in the learning process. The following
Question:
a. Based on the abstract, what are the independent variables and what are their levels?
b. What are possible dependent variables, based on the description in the abstract?
c. The researchers conducted several experiments, one of which examined students in beginning and advanced French classes. Here is the result of one analysis: The analysis also yielded the predicted expertise à feedback interaction (F(1,79) = 7.31, p < .01). Is this interaction statistically significant? Explain your answer.
d. What important statistic is missing from their report? Why would it be helpful to include this statistic?
e. The results in part (c) are represented by the graph here. We would, of course, have to conduct additional analyses to know exactly which bars are significantly different from each other. That said, what does the overall pattern seem to indicate for this analysis?
f. How would you redesign this graph in line with what you learned in Chapter 3? Give at least two specific suggestions.
