Dr. Jones is conducting research to determine if IQ changes with age. The research design includes three groups of participants:
Group 1 consists of 10 -year-olds.
Group 2 consists of 15 -year-olds.
Group 3 consists of 25 -year-olds.
Dr. Jones gives an IQ test to all three groups to determine the average IQ of each group. What is the design of the research?

Step 1:I'll solve this problem by analyzing the research design step by step:
Step 2:: Identify the Research Design Type
The research design Dr. Jones is using is a cross-sectional study. In a cross-sectional study, researchers collect data from different groups at a single point in time to compare characteristics across different age groups.
Step 3:: Analyze the Key Characteristics
- The study involves three distinct age groups:
Step 4:
Group 1: 10 -year-olds
Step 5:
Group 2: 15 -year-olds
Step 6:
Group 3: 25 -year-olds
Step 7:: Understand the Research Methodology
- Dr. Jones administers the same IQ test to all three groups - The goal is to compare IQ scores across different age groups - This allows for a comparison of cognitive abilities at different developmental stages
Step 8:: Highlight the Design's Strengths and Limitations
Strengths: - Allows quick data collection - Provides snapshot of IQ differences across age groups - Relatively low-cost and time-efficient Limitations: - Cannot track individual cognitive development over time - Potential cohort effect (differences might reflect generational variations) - Does not show how individual IQ changes with age
Final Answer
This is a cross-sectional research design comparing IQ scores across three different age groups (10, 15, and 25 years old) at a single point in time.
