MENGENAL SKALA LIKERT SEBAGAI SKALA PENGUKURAN

Summary

In this video, Khodijah Makarim introduces the Likert scale as a vital measurement tool commonly used in research to gauge perceptions, attitudes, and opinions, especially in social psychology and surveys. She explains how the Likert scale works, including its common structure (usually a 5-point scale), how it measures ordinal data, and its relevance for understanding respondent attitudes. Makarim also highlights the importance of designing clear, positive statements for ease in data analysis and advises on best practices for crafting Likert scale questionnaires, particularly for undergraduate research.

Takeaways

• 📏 The Likert scale is a measurement tool often used in research to gauge perceptions, attitudes, or opinions.
• 🔄 It is important to use one measurement tool for a single purpose; different tools are needed for different measurements.
• ⚖️ The Likert scale is psychometric, developed by social psychologist Rensis Likert, and is used to study social psychology through surveys.
• 🔢 Likert scales typically use ordinal data and are useful for measuring attitudes, perceptions, and opinions.
• 🌍 Common uses of the Likert scale include measuring opinions in social phenomena such as student perceptions, employee attitudes, and customer satisfaction.
• 👍 The scale can measure both positive and negative perceptions or attitudes and should be consistently formatted within the same questionnaire.
• 📝 Likert scales often have 5, 7, or 9 points, with 5 being the most commonly used.
• 🔄 When using a 5-point scale, the options usually range from 'strongly disagree' to 'strongly agree,' with neutral options in the middle.
• 💡 When constructing Likert scales, it's recommended to maintain either all positive or all negative statements for ease of analysis.
• 🛠 Likert scales should be derived from variables and sub-variables, with clear indicators and parameters to support accurate measurement.

Q & A

What is the Likert scale used for?

The Likert scale is used to measure attitudes, opinions, and perceptions, particularly in social science research, such as in surveys related to social psychology.

What type of data does the Likert scale measure?

The Likert scale measures ordinal data, which represents ordered categories but does not quantify the exact differences between them.

What is the origin of the Likert scale?

The Likert scale was developed by Rensis Likert, a social psychologist from the United States.

In what context is the Likert scale most commonly used?

The Likert scale is most commonly used in survey-based research to gather insights on respondents' attitudes, opinions, and perceptions, often in studies related to psychology, education, and marketing.

What are the typical response options in a Likert scale with five levels?

In a typical five-level Likert scale, the response options might be: 1. Strongly disagree, 2. Disagree, 3. Neutral, 4. Agree, and 5. Strongly agree.

How can researchers handle positive and negative statements in a Likert scale?

When using a Likert scale with both positive and negative statements, researchers must carefully assign the correct values, ensuring that positive responses align with higher values and negative responses align with lower values, to avoid confusion during data analysis.

Why is it recommended to use only positive statements in Likert scales for undergraduate research?

Using only positive statements in Likert scales is recommended for undergraduate research to simplify data analysis, as it reduces the need to track which items are positive or negative, making the process quicker and less prone to errors.

What are some common response scales used in Likert scales besides the five-point scale?

Besides the five-point scale, Likert scales can also use four-point, seven-point, or nine-point scales, with the four-point scale often eliminating a neutral option, while seven- and nine-point scales offer more granular responses.

What kind of phenomena can be measured using the Likert scale?

The Likert scale is typically used to measure social phenomena such as perceptions, attitudes, and opinions, for example, student attitudes, employee satisfaction, or customer feedback on products.

Why should Likert scale questions be consistent in format within a survey?

Likert scale questions should be consistent in format (e.g., either all statements or all questions) to ensure clarity and avoid confusing the respondents, making the data easier to interpret.
