XAT 2017 — QA & DI Question 26
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 following options is correct?
Answer & solution
- A
0.93 on the right side of the diagonal corresponds to the third scatterplot in the fourth row.
0.94 on the right side of the diagonal corresponds to the second scatterplot in the fourth row.
- C
0.38 is the relationship between "extraversion" and "true_arousal_plac".
- D
"arousal_catr” and "performance_caff" arc positively related.
- E
The line that captures relationship between "arousal_caff" and "arousal_plac" can be denoted by equation: y = a - bx, where b > 0.
Comparison between the visual pattern in the left side and the numbers in the right hand side .
Hence, option (b).
