A researcher was keen to find out whether this was due to participating in a team activity or due to participating in physical activity, as he could not find any published research on this. The researcher used a matched-pairs design. He went into the student café and selected the first 20 students he met. Each student was assigned to one of two groups. Participants in Group A were requested to carry out 3 hours of team sports per week. Participants in Group B were requested to carry out 3 hours of exercise independently in a gym each week. All participants were told not to take part in any other type of exercise for the 4-week duration of the study. All participants completed a happiness questionnaire at the start and end of the study. The researcher then calculated the improvement in happiness score for each participant. en-us 2022-04-28 06:12:53 UTC 2022-04-28 06:14:23 UTC hello@padlet.com https://study.com/cimages/videopreview/cw5j062lpk.jpg kwelsh51 https://padlet.com/kwelsh51/bggdhbcy0tqov8un/wish/2161635063 2022-04-28 06:12:53 UTC https://padlet.com/kwelsh51/bggdhbcy0tqov8un/wish/2161635063
