https://padlet.com/kwelsh51/xvrqw8osygmnybzu The psychologist decided to conduct an experiment to investigate the effect of watching horror films before going to bed. A volunteer sample of 50 university students consented to take part in the experiment. The 50 students were randomly split into two groups. Group 1 watched a horror film before going to bed each night for the first week then a romantic comedy before going to bed each night for the second week. Group 2 watched the romantic comedy in the first week and the horror film in the second week. When the students woke up each morning, each student received a text message that asked if they had had a nightmare during the night. They could respond ‘yes’ or ‘no’. en-us 2022-04-25 09:00:37 UTC 2022-04-28 09:06:18 UTC hello@padlet.com https://study.com/cimages/videopreview/cw5j062lpk.jpg kwelsh51 https://padlet.com/kwelsh51/xvrqw8osygmnybzu/wish/2156201568  The consent form should: • include some detail of what participants might expect to happen • refer to ethical issues • be in an appropriate format/style. ]]> 2022-04-25 09:10:00 UTC https://padlet.com/kwelsh51/xvrqw8osygmnybzu/wish/2156201568 kwelsh51 https://padlet.com/kwelsh51/xvrqw8osygmnybzu/wish/2156213443  What do the mean and standard deviation values in Table 3 suggest about the effect of the type of film watched on the occurrence of nightmares?
