In today’s ministry landscape, effective leadership demands not only spiritual insight but also strategic awareness of how people think, feel, and grow. As churches navigate discipleship in an increasingly digital, diverse, and data-driven world, the ability to accurately assess attitudes, experiences, and spiritual maturity is essential. Whether planning a sermon series, evaluating a small group curriculum, or developing leaders, ministers need reliable tools to understand their congregations and lead with discernment. This is where survey and measurement scales become invaluable. Far from being the exclusive domain of social scientists, these tools offer biblically grounded, ministry-minded leaders a practical framework to listen deeply, respond wisely, and shepherd faithfully.

This resource introduces ministers to 18 foundational survey scales, categorized by their function: attitude rating, choice-based feedback, matrix-style evaluations, progression assessments, linear metrics, and overarching measurement frameworks. Each scale is explained in both everyday and technical terms, equipping pastors and ministry leaders to confidently select the right method for everything from post-sermon feedback to tracking discipleship growth. By understanding how to apply Likert, Semantic Differential, Thurstone, and other specialized scales, ministers can translate subjective spiritual experiences into meaningful insights—insights that fuel transformation, foster community health, and strengthen the body of Christ.

  #

A. Core Rating & Attitude Survey Scales #

1. Likert Scale #

• Definition: A scale that measures agreement with statements using a fixed set of ordered options (e.g., 1–5, from Strongly Disagree to Strongly Agree).

• Purpose: To quantify attitudes, opinions, or agreement levels.

• Everyday Understanding: “How much do you agree with this?” Select a number or word on a list.

• Technical Understanding: An ordinal scale where response points (typically 5 or 7) are labeled to represent increasing intensity/agreement.

• Example:

  • Strongly Disagree | Disagree | Neutral | Agree | Strongly Agree

---

2. Semantic Differential Scale #

• Definition: A scale that asks respondents to rate something between two opposite adjectives.

• Purpose: To capture the intensity and direction of feelings toward a subject.

• Everyday Understanding: “Is this more good or bad? Fun or boring?”

• Technical Understanding: Bipolar endpoints (e.g., “Happy—Sad”) with a continuum of points (often 7) between, typically unlabeled except at the ends.

• Example:

  • Clean ———— Dirty

---

3. Thurstone Scale #

• Definition: A set of statements about a topic, each assigned a value by judges, with the respondent’s score based on the items they agree with.

• Purpose: To measure attitudes by identifying which statements a person endorses.

• Everyday Understanding: “Pick which statements you agree with from a list.”

• Technical Understanding: Interval-level data; judges assign favorableness weights to statements. Respondent’s mean score represents their attitude.

• Example:

  • “Chocolate is always delicious” (8)

  • “Chocolate is sometimes good” (5)

  • “Chocolate is rarely enjoyable” (2)
    
    (Pick all that apply. Average the weights.)

---

4. Stapel Scale (Spelled Correctly) #

• Definition: A vertical scale ranging from -5 to +5 with a single adjective in the center.

• Purpose: To measure attitudes toward an attribute without a negative anchor.

• Everyday Understanding: “How clean is this place, from -5 (not at all) to +5 (very)?”

• Technical Understanding: Unipolar scale, usually without a neutral zero, single adjective centered, numbers represent intensity and direction.

• Example: -5 -4 -3 -2 -1 [Clean] +1 +2 +3 +4 +5

---

5. Graphic Rating Scale #

• Definition: A scale that uses images, bars, or sliders for responses instead of numbers or words.

• Purpose: To visually capture degrees of feeling or experience.

• Everyday Understanding: “Slide the bar to show how happy you feel.”

• Technical Understanding: Continuous or discrete interval, can include icons or images as endpoints or anchors.

• Example: 😢——😐——😊 (Move the slider to your mood)

---

6. Visual Analog Scale (VAS) #

• Definition: A straight line with endpoints labeled by extremes, where respondents mark their answer anywhere along the line.

• Purpose: To measure subjective characteristics or attitudes that range across a continuum.

• Everyday Understanding: “Draw a mark on the line to show your pain.”

• Technical Understanding: A continuous interval; the position on the line is measured (e.g., 0–100 mm) for scoring.

• Example: No pain —————————————— Worst pain imaginable (Respondent marks on the line.)

---

B. Choice-Based Scales #

7. Dichotomous Scale #

• Definition: A scale offering only two opposite choices.

• Purpose: To obtain clear, decisive answers.

• Everyday Understanding: “Yes or no?” / “True or false?”

• Technical Understanding: Nominal level data with two mutually exclusive categories.

• Example: Did you finish your homework? [Yes] [No]

---

8. Multiple Choice Scale #

• Definition: Respondents select one or more answers from a fixed list.

• Purpose: To capture categorical data about preferences, facts, or experiences.

• Everyday Understanding: “Pick your favorite fruit from the list.”

• Technical Understanding: Nominal or ordinal data, depending on whether options are ordered.

• Example:

  • What is your favorite fruit?

    • Apple

    • Banana

    • Orange

---

9. Ranking Scale #

• Definition: Respondents put items in order of preference or importance.

• Purpose: To prioritize or rank choices.

• Everyday Understanding: “List your top three TV shows in order.”

• Technical Understanding: Ordinal scale; position reflects preference.

• Example:

  • Rank these in order:

    1. Apple

    2. Orange

    3. Banana

---

C. Matrix and Multi-Item Scales #

10. Multiple Rating Matrix #

• Definition: A table/grid where respondents rate several items using the same scale.

• Purpose: To collect ratings for multiple factors at once.

• Everyday Understanding: “Rate these services from 1 to 5 in a grid.”

• Technical Understanding: Efficient collection of ordinal/interval data across multiple attributes.

• Example:

---

D. Cumulative & Hierarchical Scales #

11. Guttman Scale #

• Definition: Items are ordered so that agreement with a higher-level item implies agreement with all lower items.

• Purpose: To measure the progression or intensity of an attitude or behavior.

• Everyday Understanding: “If you do the hardest thing, you probably do the easy things too.”

• Technical Understanding: Hierarchical, deterministic scale; produces ordinal data.

• Example:

  • I sometimes run.

  • I run 1 mile a week.

  • I run marathons.

---

12. Mokken Scale #

• Definition: A probabilistic version of the Guttman scale, allowing for some inconsistency.

• Purpose: To measure attitudes or traits where perfect hierarchy is unrealistic.

• Everyday Understanding: “If you score high on one item, you’re more likely (but not guaranteed) to score high on easier ones.”

• Technical Understanding: Uses item response theory; not strictly deterministic; common in psychometrics.

• Example:

  • Similar to Guttman, but not all responses follow the order.

---

13. Proximity Scale #

• Definition: Examines how responding to a harder item may influence answers to easier items.

• Purpose: To assess how item difficulty affects response patterns.

• Everyday Understanding: “Your answer to the toughest question may affect how you see the easier ones.”

• Technical Understanding: Used in psychological and mood research to assess latent traits.

• Example:

  • Items presented in increasing difficulty; responses are tracked for consistency.

---

E. Numeric/Linear Scales #

14. Linear Numeric Scale #

• Definition: A numbered scale with defined endpoints.

• Purpose: To measure intensity, frequency, or likelihood on a simple number line.

• Everyday Understanding: “Rate your satisfaction from 1 to 10.”

• Technical Understanding: Can be ordinal or interval, depending on interpretation.

• Example:

  • How likely are you to recommend us?

    • 1 (Not at all likely) … 10 (Extremely likely)

---

F. Measurement Frameworks #

15. Nominal Scale #

• Definition: Categories with no specific order.

• Purpose: To classify data by name only.

• Everyday Understanding: “What color is your shirt?”

• Technical Understanding: Only equality/inequality comparisons possible.

• Example:

  • Red, Blue, Green

---

16. Ordinal Scale #

• Definition: Ordered categories, but distances are not equal.

• Purpose: To rank or order items.

• Everyday Understanding: “Gold, silver, bronze in a race.”

• Technical Understanding: Relative order known, magnitude of difference not.

• Example:

  • 1st, 2nd, 3rd place

---

17. Interval Scale #

• Definition: Ordered categories with equal intervals but no true zero.

• Purpose: To measure with meaningful differences but no absolute zero point.

• Everyday Understanding: “Temperature in Celsius or Fahrenheit.”

• Technical Understanding: Can add/subtract; zero is arbitrary.

• Example:

  • 20°C, 30°C, 40°C

---

18. Ratio Scale #

• Definition: Ordered, equal intervals, and has an absolute zero.

• Purpose: To measure quantities where ratios are meaningful.

• Everyday Understanding: “How much money do you have?”

• Technical Understanding: Can add, subtract, multiply, divide; zero means ‘none’.

• Example:

  • 0, 10, 100 dollars

Summary: Types of Scales for Measuring Attitudes, Opinions, and Data #

Researchers and practitioners use a wide range of scales to capture attitudes, experiences, preferences, and factual information. The choice of scale depends on whether the information is best expressed as agreement, ranking, selection, intensity, or frequency, and what kind of data (categorical, ordered, numeric) is most useful for analysis.

• Likert, Semantic Differential, Thurstone, Stapel, Graphic, and Visual Analog scales are used to measure attitudes, perceptions, or intensity of feelings. They vary in structure—some use numbers, others use lines, adjectives, or even icons—but all seek to turn subjective opinions into data.

• Dichotomous, Multiple Choice, and Ranking scales are common in everyday forms, polls, and quizzes, capturing clear decisions, preferences, or orderings.

• Matrix/Multiple Rating scales help collect responses on several related items at once, making surveys more efficient.

• Guttman, Mokken, and Proximity scales are advanced tools mainly used in social science and psychological research to understand how people’s answers to more complex items relate to their answers to simpler ones.

• Numeric and Linear scales are direct and intuitive, used everywhere from customer satisfaction surveys to pain assessments in healthcare.

• Measurement frameworks (Nominal, Ordinal, Interval, Ratio) underpin all these tools, determining what statistical techniques can be used to analyze the data.

In short:

The world of measurement goes far beyond the familiar Likert scale. Each tool has a unique purpose—some for simple facts, others for nuanced feelings or scientific analysis. The best surveys and assessments choose the right scale for the right job, balancing clarity, precision, and the type of insight needed.
