https://padlet.com/kwelsh51/1vcns7s8mzkp5urg 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 2022-04-25 06:45:46 UTC 2026-02-03 16:14:42 UTC hello@padlet.com https://study.com/cimages/videopreview/cw5j062lpk.jpg kwelsh51 https://padlet.com/kwelsh51/1vcns7s8mzkp5urg/wish/2156023529 2022-04-25 06:45:46 UTC https://padlet.com/kwelsh51/1vcns7s8mzkp5urg/wish/2156023529 15packers https://padlet.com/kwelsh51/1vcns7s8mzkp5urg/wish/2156155349 non directional because the psychologist could not find any published research on this topic and would therefore not have an indication of the results.]]> 2022-04-25 08:32:56 UTC https://padlet.com/kwelsh51/1vcns7s8mzkp5urg/wish/2156155349 15packers https://padlet.com/kwelsh51/1vcns7s8mzkp5urg/wish/2156159801 there are different participants in each experimental group so there will be less chance of demand characteristics from participants working out the aim of the study. ]]> 2022-04-25 08:36:35 UTC https://padlet.com/kwelsh51/1vcns7s8mzkp5urg/wish/2156159801 15packers https://padlet.com/kwelsh51/1vcns7s8mzkp5urg/wish/2156163425 there will be a difference between happiness levels in those doing physical activity and those completing team activity ]]> 2022-04-25 08:39:44 UTC https://padlet.com/kwelsh51/1vcns7s8mzkp5urg/wish/2156163425 anonymous9876543210 https://padlet.com/kwelsh51/1vcns7s8mzkp5urg/wish/2156165200 there are no order effects and that demand is lower because all participants are tested only once]]> 2022-04-25 08:41:12 UTC https://padlet.com/kwelsh51/1vcns7s8mzkp5urg/wish/2156165200 15packers https://padlet.com/kwelsh51/1vcns7s8mzkp5urg/wish/2156166306 opportunity sampling.
