I use Accessibility Usabaility Scale on Level of Accessibility and Usability for each communication channels (television, radio, social media, government websites, and print media) in obtaining information about the provisions and benefits of the Expanded Solo Parent Welfare Act. Hence, I also useto measure the level of the level of awareness of solo parents regarding the provisions and benefits of the Expanded Solo Parent Welfare Ac using unipolar 5point likert scale. But in correlation of the two how to analyze the correlational or relationship of the two levels? level of accessiblity/usability and level of awareness?
Step-by-step approach to analyzing the relationship between the two levels:
1. Data Collection: Collect data on the level of accessibility/usability for each communication channel (television, radio, social media, government websites, and print media) using the Accessibility Usability Scale. Also, collect data on the level of awareness of solo parents regarding the provisions and benefits of the Expanded Solo Parent Welfare Act using the unipolar 5-point Likert scale.
2. Data Preparation: Assign numerical values to the Likert scale responses for the level of accessibility/usability and the level of awareness. For example, you can assign values from 1 to 5, with 1 representing low accessibility/usability or awareness and 5 representing high accessibility/usability or awareness.
3. Correlation Analysis: Calculate the correlation coefficient between the two variables (level of accessibility/usability and level of awareness). The correlation coefficient measures the strength and direction of the linear relationship between two variables. Pearson's correlation coefficient is commonly used for this purpose.
4. Interpretation of Correlation Coefficient: The correlation coefficient can range from -1 to +1. A positive correlation coefficient indicates a positive relationship, where higher levels of accessibility/usability are associated with higher levels of awareness. A negative correlation coefficient indicates a negative relationship, where higher levels of accessibility/usability are associated with lower levels of awareness. The magnitude of the correlation coefficient indicates the strength of the relationship, with values closer to -1 or +1 indicating a stronger relationship.
5. Statistical Significance: Determine the statistical significance of the correlation coefficient. This helps determine whether the observed relationship is statistically meaningful or occurred by chance. You can perform a hypothesis test, such as a t-test or p-value calculation, to assess the statistical significance.
6. Additional Analysis: Consider conducting further analyses, such as regression analysis, to explore the relationship between the variables in more detail. Regression analysis can help identify the extent to which the level of accessibility/usability predicts the level of awareness.
Hope it helps
When determining the sample size for machine learning models in anomaly detection, there's no universal formula, but several approaches can guide you. Statistical power analysis allows calculations based on desired confidence levels and effect sizes. Resampling methods like bootstrapping assess how sample size impacts model performance. Learning curves can show if more data improves results. Some practitioners follow rules of thumb, such as having examples of at least 10 times the number of features. Domain-specific considerations are crucial, as different fields may require varying amounts of data to capture all variability. Finally, the rarity of anomalies in such datasets often necessitates a larger sample size or techniques like synthetic data generation.
