A Researcher Is Interested in the Social Behavior of Mice

question 8

Multiple Choice

A researcher is interested in the social behavior of mice. He hypothesizes that mice from Strain A will be more social than mice from Strain B, and Strain B will be significantly more social than mice from Strain C. Mice from each of the three different strains (20 mice in each strain) are raised in a laboratory. The mice are group housed with members of its own strain. All the mice receive the exact same amount of food, water, and light over the first 10 weeks of life. At 11 weeks of age, each mouse is placed in a cage with a novel mouse from his own strain. The mouse's investigatory behavior toward the other mouse is timed for 10 minutes.
Which statistical analysis is most appropriate for testing this researcher's hypothesis?

• A) One-way ANOVA
• B) Repeated-measures ANOVA
• C) Factorial ANOVA
• D) Independent samples t-test

Definitions:

Base

In chemistry, a base is a substance that can accept protons (H+) from acids or donate a pair of valence electrons to form a bond, and it often has a high pH when dissolved in water.

Dissociates

Refers to the process by which molecules or ionic compounds split into smaller particles, often ions, in solution.

Rainwater

Water precipitated from clouds in the form of rain, often considered as a natural source of relatively clean water.

Acidic

A description for substances with a pH less than 7, indicating a higher concentration of hydrogen ions (H+) than water.
