Bar graphs are used to interpret results in an experiment by comparing the change of the dependent variable under different scenarios. D) on dark-colored soil with full moonlight.
How to interprete a bar graph?
A bar graph represents the relationship between two variables, the dependent and the independent one.
Usually,
- Independent variable ⇒ X axis
- Dependent variable ⇒ Y axis
Bars represent how the dependent variables react or respond to changes in the independent variable.
These charts are used to make comparisons. This means that by looking at the different bars, the researcher can to compare how the dependent variable responds under different scenarios of the independent variable. For instance, in which situation the bar is higher or shorter.
Bar graphs turn out to be an easy and reliable way to interpret results in an experiment.
Now let us analyze this example,
The researcher compares how many mice were caught by the owl under different scerarios: different substrate color, under moonlight or not, and according to their coat color.
- Coat color: white and brown
- Substrate: light and dark
- Moonlight: Full moon - No moon
The dependent variable is the number of caught mice, which depends on coat color, moonlight, and substrate color.
The independent variables are coat color, moonlight, and substrate color. Any change in them will affect the dependent variable.
Notice that even when the researcher can not manipulate the coat color, this is also an independent variable.
The question asks under which conditions would a dark brown mouse be most likely to escape predation at night?
Well, to answer it, we just need to compare the bars height.
- Higher bars means a higher number of caught mice
- Lower bars means that mice managed to scape predation
Since the question ONLY asks about brown mice, we will limit out interpretation to brown bars.
- The shortest brown bar reflects that on dark soil and under a full moon, the number of brown caught mice was the lowest, with only about 12 individuals eaten.
- The highest brown bar reflects that on light soil, and under no moon, the number of brown caught mice was the highest, with about 37 animals eaten.
The bar that expresses the conditions under which brown mice managed to scape predation is the shortest one, because it tells us about the lowest number of individuals caught by the owl.
So the answer to this question is on dark-colored soil with full moon light. Option D).

Complete question: Image in the attached files
Pairs of mice (Peromyscus polionotus) with different coat colours, one light brown and one dark brown, were released simultaneously into an enclosure that contained a hungry owl.
The researcher recorded the colour of the mouse that was first caught by the owl. If the owl did not catch either mouse within 15 minutes, the test was recorded as a zero.
The release trials were repeated multiple times in enclosures with either a dark-coloured soil surface or a light-coloured soil surface.
The presence or absence of moonlight during each assay was recorded.
(a) Under which conditions would a dark brown mouse be most likely to escape predation at night?
a. on light-coloured soil with no moon
b. on dark-coloured soil with no moon
c. on light-coloured soil with full moon light
d. on dark-coloured soil with full moon light
