https://padlet.com/kwelsh51/apptgt2uan3r2v56 It was recently reported in a newspaper that time spent playing team sports increases happiness levels. 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 2022-04-22 12:02:39 UTC 2022-04-22 13:12:29 UTC hello@padlet.com https://study.com/cimages/videopreview/cw5j062lpk.jpg kwelsh51 https://padlet.com/kwelsh51/apptgt2uan3r2v56/wish/2153492017 2022-04-22 12:06:34 UTC https://padlet.com/kwelsh51/apptgt2uan3r2v56/wish/2153492017 https://padlet.com/kwelsh51/apptgt2uan3r2v56/wish/2153556755 Non-directional as no previous 'published research' had been done ]]> 2022-04-22 13:04:11 UTC https://padlet.com/kwelsh51/apptgt2uan3r2v56/wish/2153556755 https://padlet.com/kwelsh51/apptgt2uan3r2v56/wish/2153558212 There will be a significant difference between the happiness level of group A doing team sports and group B doing independent sports. ]]> 2022-04-22 13:05:18 UTC https://padlet.com/kwelsh51/apptgt2uan3r2v56/wish/2153558212 https://padlet.com/kwelsh51/apptgt2uan3r2v56/wish/2153559706 Opportunity sample 
One limitation is that it is not representative of the wider population, as they group of students he picked may not enjoy sports at all. ]]> 2022-04-22 13:06:27 UTC https://padlet.com/kwelsh51/apptgt2uan3r2v56/wish/2153559706 https://padlet.com/kwelsh51/apptgt2uan3r2v56/wish/2153561420 They could be matched on the hours of current exercise they perform each week.
