https://padlet.com/kwelsh51/4zwxn6q9k74zao27 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 12:13:33 UTC 2022-04-22 13:32:53 UTC hello@padlet.com https://study.com/cimages/videopreview/cw5j062lpk.jpg kwelsh51 https://padlet.com/kwelsh51/4zwxn6q9k74zao27/wish/2153502034 2022-04-22 12:17:09 UTC https://padlet.com/kwelsh51/4zwxn6q9k74zao27/wish/2153502034 kwelsh51 https://padlet.com/kwelsh51/4zwxn6q9k74zao27/wish/2153507368 2022-04-22 12:21:57 UTC https://padlet.com/kwelsh51/4zwxn6q9k74zao27/wish/2153507368 https://padlet.com/kwelsh51/4zwxn6q9k74zao27/wish/2153570446 When a new test has strong agreement against a well-established already valid test. ]]> 2022-04-22 13:14:29 UTC https://padlet.com/kwelsh51/4zwxn6q9k74zao27/wish/2153570446 https://padlet.com/kwelsh51/4zwxn6q9k74zao27/wish/2153572427 The researcher was open to bias, as they knew they expected to find greater happiness levels in group A, the group performing team sports. ]]> 2022-04-22 13:15:59 UTC https://padlet.com/kwelsh51/4zwxn6q9k74zao27/wish/2153572427 https://padlet.com/kwelsh51/4zwxn6q9k74zao27/wish/2153590986 They could use a double blind trial in which neither the researcher or participant knows which group they are in. This then removes any bias as the researcher can not look for what they expect to find.
