In a study similar to the one in Exercise 6.15, Latané and Dabbs (1975) had a confederate enter an elevator and then “accidentally” drop a handful of pencils. They then noted whether bystanders helped pick them up. The data tabulate helping behavior by the gender of the bystander:

What could Latané and Dabbs conclude from the data? (Note that when we collapse over gender, only about one-quarter of the bystanders helped. That is not relevant to the question, but it is an interesting finding that could easily be missed by routine computer-based analyses.)
