Chapter 13 discussed whether children's poor memory performance can be traced to faulty metamemory and ineffective use of memory strategies. According to this discussion,
a. the correlation between metamemory and memory performance is extremely high. b. the correlation between metamemory and strategy use is high, but neither of these two factors is correlated with memory performance. c. the correlation between metamemory and memory performance is moderate, and it would probably be higher if we could accurately measure children's metamemory. d. none of the appropriate correlations is statistically significant, so some other factorâ€"other than metamemory accuracy and strategy useâ€"must account for children's memory deficits.
When two variables are correlated, one variable may or may not be causing the other
