12.12 Quick review questions
A study on the bruising of apples (Doosti-Irani et al. 2016) purposefully hit apples with three different forces (200, 700 and 1200 mJ), in three different regions of the apple (lower; middle; upper). The researchers then recorded the depth of the bruising, to determine if the bruise depth could be estimated from the recorded the surface temperature at the bruise location.
- Which one of the following could be used to graph the response variable?
- Which one of the following could be used to graph the explanatory variable?
- Which one of the following could be used to graph the relationship between the response and explanatory variables?
- Which one of the following could be used to graph the relationship between the ‘surface temperature’ and ‘bruise location?’
