A developmental psychologist records the favorite color (e.g., blue, red, green) of 50 preschoolers. What specific statistical value should the psychologist report to summarize the central tendency of these favorite colors, and what will that value represent?
Question: A developmental psychologist records the favorite color (e.g., blue, red, green) of 50 preschoolers. What specific statistical value should the psychologist report to summarize the central tendency of these favorite colors, and what will that value represent?
Sample answer: The psychologist should report the mode, which will represent the specific color category that was chosen by the highest number of preschoolers.
Key points:
- The researcher should report the mode.
- The mode represents the most frequently occurring score or category.
- In this context, it represents the color chosen by the highest number of preschoolers.
Rubric: Full credit is given for identifying the mode and applying its definition to represent the most frequently chosen color category.

Example of a Mode
Which of the following is a unique characteristic of the mode compared to other measures of central tendency?
Match each term related to the mode with the statement that best describes its role in summarizing psychological research data.
In a study on student stressors, 'Exams' currently has 20 responses and 'Financial Stress' has 18 responses. If three more students are surveyed and they all choose 'Financial Stress' as their primary stressor, the mode of the distribution shifts from 'Exams' to 'Financial Stress.'
A researcher is tracking the 'preferred research method' among a group of students in a seminar. Sequence the following events to analyze how the mode of this categorical distribution changes as new data is incorporated into the study.
A researcher is studying the 'primary attachment style' (e.g., Secure, Anxious, Avoidant) in a sample of infants and reports the mode as 'Secure.' A colleague critiques the report, arguing that the researcher should have calculated the mean attachment style to provide a more 'mathematically rigorous' summary of the group's central tendency. Evaluate the validity of this critique.
The mode is the value or category that occurs with the highest frequency in a distribution.
A group of psychology students is analyzing different sets of data collected in their research methods lab. Match each researcher's dataset with the correct mode for that distribution.
A researcher is recording the 'primary coping strategy' (e.g., exercise, meditation, or social support) used by college students. Because these data are categorical rather than numerical, the researcher should identify the _____ to determine which specific coping strategy was most frequently reported.
A psychology student collecting data on participants' primary coping strategy (e.g., exercise, sleep, or therapy) needs to summarize the central tendency of this distribution. To analyze this categorical dataset, the researcher must identify the _____ of the distribution, as it is the only measure of central tendency capable of summarizing non-numerical categories.
A researcher is evaluating which measure of central tendency is the most appropriate to summarize participants' preferred learning formats (e.g., visual, auditory, or hands-on). Order the steps the researcher should take to evaluate and select the correct measure.
Define the mode as a measure of central tendency and explain its unique capability compared to the mean and median.
Based on the type of data collected in this study, which measure of central tendency must the researchers use, and why is it the only appropriate choice?
