A researcher is interested in the impact of social media on self esteem. More specifically, she is interested in understanding if certain social media platforms have a greater impact on self esteem in comparison to others. To test her hypothesis, she recruits participants and randomly assigns them to one of two groups - one using only Instagram for a month and the other using only Twitter for a month. After a month, she measures self esteem using a questionnaire and checks if there is any difference.
Null: There is no significant difference between the impact of
Instagram and Twitter on self esteem.
Alternative: There is a significant difference between the impact of Instagram and Twitter on self esteem
Type I Error: Finding in the study that there is a significant difference between the impact of Instagram and Twitter on self esteem, when in reality, there is no such difference.
Type II Error: Finding in the study that there is no significant difference between the impact of Instagram and Twitter on self esteem, when in reality, there is such a difference.
