Question 253

A cognitive psychologist investigated whether a new structured-visualization technique improves the number of facts recalled from a text compared to a standard rote-rehearsal strategy.

Group A (Experimental): Used the structured-visualization technique ( $N_1 = 7$ )
Group B (Control): Used rote-rehearsal ( $N_2 = 6$ )

The calculated value of $U\,$ was found to be 9.

Table 1: Critical Values of $U\,$ for a One-Tailed Test at $\le 0.05$

$N_1$	$N_2 = 5$	$N_2 = 6$	$N_2 = 7$
5	4	5	6
6	5	7	8
7	6	8	11

Using the information provided in Table 1, explain whether the structured-visualization technique was significantly effective in improving fact recall.
