Final answer:
The standard deviation helps in the interpretation of whether the crimson topaz and the fiery topaz are different species of hummingbird or different forms of the same species.
Step-by-step explanation:
In the investigation of whether the crimson topaz and the fiery topaz are different species of hummingbird or different forms of the same species, the standard deviation can help in the interpretation of the data. Standard deviation measures the spread of data points from the mean, providing information about the variability within the data set. By calculating the standard deviation of various traits or characteristics of the crimson topaz and the fiery topaz, biologists can assess the extent of differences or similarities between the two hummingbirds. A smaller standard deviation suggests that the crimson topaz and the fiery topaz are more similar in certain traits, supporting the possibility that they are different forms of the same species. On the other hand, a larger standard deviation indicates greater variability, implying that the crimson topaz and the fiery topaz may be different species of hummingbird.
