Today, we will discuss the vital characteristics of quantitative research. Can anyone tell me what makes quantitative research distinct?
It uses numbers and stats, right?
Exactly! Quantitative research focuses primarily on objective measurement and statistical analysis. What do you think is an example of quantitative data?
Census data could be an example!
Great example! Another important characteristic is that quantitative research relies on large sample sizes which helps in achieving statistical validity. Remember the acronym OLS – Objective, Large samples, Statistical validity. Can anyone expand on statistical validity?
It means the results can be applied to the general population?
Correct! In summary, quantitative research is defined by its objective nature, use of extensive data, and its reliance on statistics to validate findings.

Now let’s shift gears and discuss qualitative research. What stands out about qualitative research compared to quantitative?
It focuses more on understanding people's feelings and experiences?
Exactly! Qualitative research is all about subjective interpretation. It works with smaller sample sizes, but digs much deeper. Why do you think that depth is important?
It helps to understand the 'why' behind behaviors.
Well said! Also, examples like ethnographies and in-depth interviews highlight this depth of understanding. Remember the mnemonic SOM for Subjective, Obscure details, and Meaningful insights. Can anyone think of a downside to qualitative methods?
Maybe they aren't as generalizable?
Correct indeed! In conclusion, qualitative research provides rich insights, but without the broader application seen in quantitative research.
Introduction & Overview
Read summaries of the section's main ideas at different levels of detail.
Quick Overview
Standard
The section highlights how quantitative research emphasizes objective measurement and large sample sizes, whereas qualitative research focuses on subjective interpretation and smaller sample sizes. Understanding these characteristics is crucial for selecting the appropriate research methodology in social sciences.

Characteristics of Research Methods
In the realm of social sciences, research is typically divided into two primary methodologies: qualitative and quantitative research.
Quantitative Research Characteristics:
- Objective Measurement: It seeks numbers and statistics, making it an effective method for testing hypotheses.
- Large Sample Sizes: The aim is to ensure findings can be generalized.
- Statistical Validity: It provides solid evidence and allows for the application of inferential statistics.
Examples of Quantitative Research include:
- Census Data: Collecting demographic information from a population.
- Public Opinion Surveys: Capturing the sentiments of a larger group.
Qualitative Research Characteristics:
- Subjective Interpretation: Focuses on depth and understanding of human experiences.
- Smaller Sample Sizes: Because of the in-depth exploration of individual cases or events.
- In-Depth Understanding: It provides insights into motivations, feelings, and social contexts.
Examples of Qualitative Research include:
- Ethnographies: Detailed descriptions of cultures or communities.
- In-Depth Interviews: Conversations that probe deeper into personal perspectives.
This distinction is vital for researchers to choose appropriate methodologies for their studies, influencing the research's direction, implementation, and analysis. By recognizing the characteristics of each method, researchers can better design their studies and understand the implications of their chosen approach.

● Objective measurement.
Detailed Explanation
Objective measurement refers to collecting data in a way that is not influenced by personal feelings or opinions. This method ensures that the findings are based on observable phenomena, which can be verified by others. In quantitative research, objective measurement often relies on instruments that produce numerical results, such as scales or devices that record statistics.
Examples & Analogies
Think of objective measurement like a thermometer measuring temperature. No matter who uses it, the thermometer will always read the same temperature if in the same environment, ensuring accuracy and consistency.
Large Sample Sizes

● Large sample sizes.
Detailed Explanation
Using large sample sizes in research enhances the validity of the results because it captures a diverse range of opinions and behaviors. When the sample size is larger, the findings can be more generalizable to the larger population. This is crucial in quantitative research as it helps to reduce the impact of anomalies or outliers that might skew the results.
Examples & Analogies
Imagine polling a small group of friends about their favorite pizza toppings. If only six people respond, their choices might not reflect the preferences of the entire neighborhood. However, if you gather responses from hundreds of people, the results will likely provide a more accurate picture of what everyone prefers.
Statistical Validity

● Statistical validity.
Detailed Explanation
Statistical validity refers to the trustworthiness of the statistical conclusions drawn from the data. It ensures that the results from the data analysis accurately reflect the relationships and patterns in the larger population. To achieve statistical validity, researchers use appropriate statistical methods and analyses that match the study design and questions.
Examples & Analogies
Consider a sports team's performance statistics over a season. If they only look at a couple of games (poor statistical validity), they might conclude that they're the best team based on those games alone. However, analyzing the entire season's results provides a more accurate and valid assessment of their performance.
Key Concepts
-
Objective Measurement: The emphasis on quantifying data to test hypotheses.
-
Subjective Interpretation: The focus on understanding the depth of human experiences through lived narratives.
-
Statistical Validity: Ensuring the reliability of quantitative research findings for broader applications.
Examples & Applications
Census Data: Collecting demographic information from a population.
Public Opinion Surveys: Capturing the sentiments of a larger group.
Qualitative Research Characteristics:
Subjective Interpretation: Focuses on depth and understanding of human experiences.
Smaller Sample Sizes: Because of the in-depth exploration of individual cases or events.
In-Depth Understanding: It provides insights into motivations, feelings, and social contexts.

Ethnographies: Detailed descriptions of cultures or communities.
In-Depth Interviews: Conversations that probe deeper into personal perspectives.
