13D Research Methods: Nov 2020 Exam Paper Q17-23 by KJ Welsh https://padlet.com/kwelsh51/mr4kdk1xuara7fbe The psychologist decided to design an experiment to test the effects of recreational screen time on children’s academic performance. The psychologist randomly selected four schools from all the primary schools in her county to take part in the experiment involving Year 5 pupils. Three of the four schools agreed to take part. In total, there were 58 pupils whose parents consented for them to participate. The 58 pupils were then randomly allocated to GROUP A or GROUP B. For the two-week period of the experiment, pupils in GROUP A had no recreational screen time. Pupils in GROUP B were allowed unrestricted recreational screen time. At the end of the experiment all pupils completed a 45-minute class test, to achieve a test score. en-us 2022-04-21 14:35:18 UTC 2025-09-25 13:10:39 UTC hello@padlet.com https://study.com/cimages/videopreview/cw5j062lpk.jpg Table 1: Cut and past this word table into your response adding the check marks in the appropriate column kwelsh51 https://padlet.com/kwelsh51/mr4kdk1xuara7fbe/wish/2153261218 2022-04-22 07:44:38 UTC https://padlet.com/kwelsh51/mr4kdk1xuara7fbe/wish/2153261218 Table 2: The results obtained from the experiment are summarised in Table 2. kwelsh51 https://padlet.com/kwelsh51/mr4kdk1xuara7fbe/wish/2153276259 2022-04-22 07:58:59 UTC https://padlet.com/kwelsh51/mr4kdk1xuara7fbe/wish/2153276259
