Recent research indicates that the effectiveness of antidepressant medication is directly related to the severity of the depression (Khan, Brodhead, Kolts & Brown, 2005). Based on pretreatment depression scores, patients were divided into four groups based on their level of depression. After receiving the antidepressant medication, depression scores were measured again and the amount of improvement was recorded for each patient. The following data are similar to the results of the study. Run the single-factor ANOVA for this data: Low...

The first two questions refer to the following information: Researchers developed an online tool to help ESL students learn prepositions and metaphors. A study measuring academic success in ESL students randomly sampled 100 Spanish speaking ESL students using traditional ESL classes and the new language tool and 81 Portuguese speaking ESL students using traditional ESL classes and the new language tool, and scored them on a common English fluency scale (higher score representing greater degree of fluency). The researchers suspected...

Future Time Orientation and Condom Use for AIDS
Prevention
Background Notes: Researchers administered questionnaires to
male college students taking an introductory psychology course.
Among other things, they measured future time orientation defined
as planning ahead for future events and willingness to delay
gratification. (Sample item: “I believe that a person’s day should
be planned ahead.”) Based on the scores on the future time
orientation scale, they split the male students into two groups –
one low in future orientation and...

The manager wants to know what effect the frequency at which opponents are released by the computer has on the length of time players survive in the game. A large group of playtesters is available, most of whom already have some experience playing the new game, and each is randomly allocated to play the game with a different opponent release frequency Data was collected for the variables...

Can you please explain in simple terms the methods of this experiment? I'm having difficulty visualizing and understanding what is being done. I have copied and pasted some of the text from the article. Thank you! Abstract : Obesity, high-fat diets, and subsequent type 2 diabetes (T2DM) are associated with cognitive impairment. Moreover, T2DM increases the risk of Alzheimer's disease (AD) and leads to abnormal elevation of brain beta-amyloid levels, one of the hallmarks of AD. The psychoactive alkaloid caffeine...
