A lot of researchers in Behavioral Sciences are interested in a phenomenon called "Bystander Intervention" This is basically exploring the idea of strangers stepping in to help a bystander who may need it. So imagine that a researcher set up an experiment in a local shopping mall. They had a person walk through the mall and trip and fall, spilling all their packages and laying on the floor. Researchers hired several assistant to observe who would step in to help. They were mainly interested in whether men or women would be more likely to help. Also, they wanted to explore whether the age of the "helper" would matter. The collected observational data and after the noting those that did step in to help, they were asked to report their age. The data collected for this experiment are presented below. Use the data below and on a separate sheet of paper, complete the assignment. Sample Ages of Males who Helped Ages of Females who helped Apparent Frequency Limits Apparent Frequency Relative Limit Frequency 60-64 0 60-64 14 55-59 0 55-59 45 50-54 1 50-54 33 45-49 6 45-49 25 40-44 15 40-44 20 35-39 20 35-39 12 30-34 40 30-34 5 25-29 46 25-29 1 20-24 24 20-24 3 15-19 8 15-19 2 n=160 n= 160 Researchers investigated the effect of gender and age on "helping behavior". The number of females and males who stopped to help were counted. The data are presented in the group frequency distribution.
