XAT 2017 — QA & DI Question 24
Answer the next 4 questions based on the following information:
The grid below captures relationships among seven personality dimensions: "extraversion", "true_arousal_plac", "true_arousal_caff”, "arousal_plac", "arousal_caff”, "performance_plac", and "performance caff”. The diagonal represents histograms of the seven dimensions. Left of the diagonal represents scatterplots between the dimensions while the right of the diagonal represents quantitative relationships between the dimensions. The lines in the scatterplots are closest approximation of the points. The value of the relationships to the right of the diagonal can vary from -1 to +1, with -1 being the extreme linear negative relation and +1 extreme linear positive relation. (Axes of the graph are conventionally drawn).
âââââââ
Which of the scatterplots shows the weakest relationship?
Answer & solution
Between "extraversion" and "performance_caff".
- B
Between "true_arousal_plac" and "arousal_plac".
- C
Between "true_arousal_plac" and "performance_plac".
- D
Between "true_arousal_caff" and "performance_caff".
- E
Between "arousal_caff" and "performance_caff".
The weakest relationship should have relationship value close to zero.
The closest relationship to zero, among the five options, is 0.16, which is between extraverion and performance_caff.
Hence, option (a).
