Question Variables

  1. Choice Questions, Drop downMenu Questions, Icon Selection Questions, Image Selection Questions, Hotspot Questions
  1. Rating Scale Questions, Point Allocation Questions, Continuous Scale Questions
  • The options can correspond to Category and Numbers variables for quantitative or numerical analysis. Quantitative analysis is based on the possible scores appearing in the results, such as how many people have assigned a certain score.
  1. Ranking Questions
  • The question corresponds to Matrix Category and Matrix Numbers variables, allowing for quantitative or numerical analysis of all options. The options correspond to Category and Numbers variables based on the question variable type, with the analysis type being the same as that for rating questions.
  1. Matrix Questions
  • The options correspond to Category variables, and quantitative analysis can be conducted based on whether they are selected.
  1. Cascading Dropdown Questions
  • Since cascading questions are constructed using menu questions, the first-level menu question, serving as the primary menu for the cascading question, does not have a corresponding variable. The second-level menu question, used as the secondary menu, is equivalent to a multiple-choice question. The question corresponds to a Checkboxes type variable for quantitative analysis. The options correspond to Category variables, with quantitative analysis being conducted based on whether each individual option is selected.

Types of Data Analysis

  • Describe: Statistical analysis of a single variable.
  • Relate: Cross-analysis of two variables.
  • Quantitative Analysis: Focuses on category-based analysis derived from sample size, yielding information such as category-based counts and percentages. Most analyses are based on this type.
  • Numerical Analysis: Analysis centered around numerical values, yielding results such as average, median, variance, maximum, minimum, percentage, and bar charts showing numerical distribution.

Notes
Price Sensitivity Meter (PSM)
  1. Price Elasticity: The degree to which changes in price affect consumers' purchasing intentions. By calculating changes in purchasing intentions at different price points, the price elasticity of the product can be assessed.
  2. Optimal Price Range: The price range that maximizes profits. Within this range, consumers will not refuse to purchase due to high prices, nor will the company lose too much profit due to low prices.
  3. Pricing Strategy Recommendations: Based on consumer feedback and data analysis, the PSM model can also provide specific pricing strategy recommendations, such as whether to conduct price promotions or introduce products at different price levels.
Notes
  1. Purchasing Power Consideration: Although the PSM model considers consumers' acceptance levels, it may overlook their purchasing power. Therefore, when formulating pricing strategies, it is also necessary to comprehensively consider the purchasing power of the target consumer group.
  2. Sample Size Selection: To avoid the influence of random errors, the sample size should be sufficiently large and representative. At the same time, attention should be paid to the rationality of the questionnaire or interview design and the accuracy of data collection.
  3. Lack of Competitor Information: A limitation of the PSM model is that it does not consider competitor information. In some cases, competitors' prices and positioning may have an important impact on consumers' purchasing decisions. Therefore, when formulating pricing strategies, it is also necessary to analyze and judge based on the market environment and competitor conditions.
Kano Model
    • Also known as basic quality or threshold attributes. These are functions or services that a product must provide; if not, users will be very dissatisfied. They are the threshold for a product to enter the market and are considered essential by consumers.
    • Examples: Calling function and safety performance of mobile phones; guest rooms and catering services provided by high-star hotels.
    • Also known as unary quality or performance attributes. When a product provides such functions or services, user satisfaction will increase; conversely, if not provided, user satisfaction will decrease.
    • Examples: Users will be very satisfied if a mobile phone has a long standby time and strong signals; guests will be satisfied if a hotel provides standard services expected by customers.
    • Also known as exciting quality or motivators. Even if such functions or services are not provided, user satisfaction will not decrease; however, when provided, user satisfaction will greatly increase, sometimes even guaranteeing the competitiveness of the product or service.
    • Examples: A mobile phone with additional smart sharing features will outperform traditional mobile phones.
    • Whether such functions or services are provided or not, there will be no significant change in user satisfaction. In cases of limited resources, such functions or services can be prioritized lower.
    • Examples: Gifts provided by airlines or hotels that have no practical value to customers.
    • Users do not have such needs, and providing them will lead to decreased satisfaction.
    • Examples: Over-servicing can cause反感 among many customers.
Notes
  1. Needs vary from person to person, so it is important to meet the needs of the majority within the target customer group.
  2. Needs may differ due to cultural differences, so the impact of cultural differences on product needs should be considered.
  3. Needs change over time, and what was once a one-dimensional or attractive need may today have become a must-be need. Therefore, companies need to continuously investigate needs and iterate their products.
Pearson Correlation Analysis
  • r=1 indicates a perfect positive correlation, meaning an increase in one variable is accompanied by an equivalent increase in the other.
  • r=-1 indicates a perfect negative correlation, meaning an increase in one variable is accompanied by an equivalent decrease in the other.
  • r=0 indicates no linear relationship between the two variables.
  1. Continuous Variables: Both variables should be continuous, meaning they can take any real numerical value.
  2. Linear Relationship: The relationship between the two variables should be linear, meaning changes in one variable can be approximately described by a linear function of the other.
  3. Normal Distribution: The data should come from a normally distributed or nearly normally distributed population. If the data does not conform to a normal distribution, the calculation of the correlation coefficient may be biased or inaccurate.
  1. Exploratory Data Analysis: In the initial stage of data analysis, the Pearson correlation coefficient can help identify which variables may have a linear relationship, providing clues for subsequent analysis.
  2. Hypothesis Testing: In statistics, by constructing statistical quantities and consulting tables to obtain critical values, one can determine whether the Pearson correlation coefficient is significantly different from zero, thereby indicating whether there is a linear relationship between the two variables.
  3. Prediction and Modeling: In statistical modeling such as regression analysis, the Pearson correlation coefficient can be used as one of the bases for selecting independent and dependent variables, as well as an indicator for assessing the predictive ability of the model.
Notes
  1. Nonlinear Relationships: The Pearson correlation coefficient can only measure linear relationships and cannot accurately reflect nonlinear relationships (such as curved relationships, exponential relationships, etc.).
  2. Outliers: Outliers (such as extreme values or isolated points) may have a significant impact on the calculation of the Pearson correlation coefficient. Therefore, attention should be paid to data cleaning and preprocessing when conducting correlation analysis.
  3. Causality: The Pearson correlation coefficient can only indicate the existence of a linear relationship between two variables but cannot explain the causality between them. Therefore, caution is needed when interpreting correlation results.
Importance-Performance Analysis (IPA)
  1. Quadrant A (Maintain and Enhance Area): The attributes located in this quadrant are highly valued by customers and are performed satisfactorily by the business. These attributes are the strengths of the enterprise and should be maintained and further enhanced to consolidate market position.
  2. Quadrant B (Over-Supplied Area): The attributes in this quadrant are not highly valued by customers but are performed satisfactorily by the business. These attributes may consume excessive resources of the enterprise without bringing corresponding improvements in customer satisfaction. Therefore, the enterprise may consider appropriately reducing or optimizing these attributes to allocate resources to areas that require more improvement.
  3. Quadrant C (Low Priority Area): The attributes in this quadrant are neither highly valued by customers nor performed satisfactorily by the business. Although these attributes have a certain impact on customer satisfaction, they are not critical factors. Therefore, in cases of limited resources, enterprises can prioritize the improvement of these attributes lower.
  4. Quadrant D (Focus on Improvement Area): The attributes in this quadrant are highly valued by customers but are not performed satisfactorily by the business. These attributes are key areas that require urgent improvement by the enterprise. By enhancing the performance of these attributes, enterprises can significantly improve customer satisfaction and loyalty.
  1. Determine Evaluation Factors: Based on customer needs and service characteristics, determine the various factors for evaluating the service.
  2. Design Questionnaires: Develop questionnaires for customers to rate the importance and satisfaction of each service factor. The Likert scale is often used for rating.
  3. Collect Data: Collect customers' evaluation data through questionnaires.
  4. Analyze Data: Plot the data on the IPA matrix to form four quadrants. This step usually requires the use of statistical software (such as SPSS) for data visualization and analysis.
  5. Formulate Strategies: Based on the analysis results of the IPA matrix, formulate improvement strategies to optimize services. Focus on improving attributes in Quadrant D, while maintaining the strengths of attributes in Quadrant A, and considering optimizing or reducing attributes in Quadrants B and C.
