    Study Notes

    Determining the Association between Gender and Student Performance

    • The teacher wanted to investigate if female students perform better than male students in a certain subject
    • The teacher collected data from 20 students, including their gender and scores out of 100
    • The data was divided into two groups based on gender: 12 female students and 8 male students
    • Visualization of the data showed:
      • In the first dataset, female and male students had scores within a similar range
      • In the second dataset, female students generally scored higher than male students
    • To quantify the strength of the association between gender and performance:
      • The teacher coded gender as a dichotomous variable (0 for male, 1 for female)
      • Calculated the mean scores for each gender group (78.66 for females, 82.25 for males)
      • Calculated the point-biserial correlation coefficient, which was 0.188 in the first dataset and -0.963 in the second dataset
      • The sign and magnitude of the point-biserial correlation coefficient indicates the strength and direction of the association between gender and performance
      • A strong positive or negative correlation close to 1 or -1 suggests a strong association

    Research Question

    • The teacher investigated whether female students outperform male students in a specific subject

    Data Collection

    • 20 students' data collected, including gender and scores out of 100
    • Data divided into two groups: 12 female students and 8 male students

    Data Visualization

    • Female and male students had similar score ranges in the first dataset
    • Female students generally scored higher than male students in the second dataset

    Quantifying Association

    • Gender coded as dichotomous variable: 0 for male, 1 for female
    • Mean scores calculated for each gender group: 78.66 for females, 82.25 for males
    • Point-biserial correlation coefficient calculated: 0.188 in the first dataset, -0.963 in the second dataset

    Interpreting Correlation Coefficient

    • Sign and magnitude of coefficient indicate strength and direction of association between gender and performance
    • Strong positive or negative correlation close to 1 or -1 suggests a strong association
