Solution
In this study, the types of validity that were not established are external validity and construct validity.
External validity refers to the extent to which the findings of a study can be generalized to a larger population or real-world settings. In this study, the participants were recruited online, which may not represent the entire population. Additionally, the study only focused on the effects of watching cat videos on stress levels, so the generalizability to other types of videos or stimuli is not established.
Construct validity refers to the extent to which the study accurately measures the intended construct or concept. In this study, the construct of stress was measured using a 5-item questionnaire. However, the questionnaire's validity and reliability were not discussed, so it is unclear if it accurately captures participants' stress levels.
On the other hand, the study reasonably met the criteria for statistical validity and internal validity.
Statistical validity refers to the extent to which the statistical analysis accurately represents the data and supports the conclusions drawn. In this study, a statistical test was conducted, which showed a strong effect of watching cat videos on reducing stress. This suggests that the statistical analysis was appropriate and supported the findings.
Internal validity refers to the extent to which the study design and procedures minimize confounding factors and allow for causal inferences. In this study, participants were asked to watch a video of kittens and then complete a questionnaire about their stress levels. This sequential order suggests a cause-and-effect relationship between watching the video and reduced stress. However, without further information about the study design and control of confounding variables, it is difficult to fully assess the internal validity.
Overall, while the study reasonably met the criteria for statistical validity and internal validity, external validity and construct validity were not fully established.

does using social media stress us out? Participants were randomly assigned to either use Facebook daily or to quit the social media platform entirely for 5 days. After this the participants measured a variety of measures of stress, including rating their stress on a scale from 1 (low stress) to 5 (high stress). For the participants who were to use Facebook daily the mean was 3.145 with a sum of squares equal to 3.16 (n = 10). For the participants who didn’t use Facebook for 5 days the mean was 2.478 with a sum of squares equal to 4.17 (n = 10). The data were normally distributed and the homogeneity of variance assumption was met. Use an = .05, two tailed test.
