3. For the following variables, state whether they are nominal, ordinal, interval, or ratio:GenderNumber GradeLetter Grade The dataset displayed contains various columns representing student performance metrics. Below is a transcription and explanation of each component:### Columns:1. **Student ID**: Numerical identifier for each student (1 to 29).2. **Gender**: Binary indicator (0 or 1) for gender.3. **Exam 1, Exam 2, Exam 3**: Scores from three different exams.4. **Homework**: Score obtained in homework.5. **Lab**: Score obtained in lab assignments.6. **Number Grade**: Overall numerical grade calculated as an average or weighted average of scores.7. **Letter Grade**: Grade represented in letter format (A to E) based on the number grade.8. **Z-Score**: Standard score indicating how many standard deviations an element is from the mean.9. **Abs Z-Score**: Absolute value of the Z-score, showing the magnitude of deviation from the mean.### Summary of the Table:- The dataset is organized by rows for individual students and includes respective scores for exams, homework, and lab performances. - Grades are represented both numerically and alphabetically for a comprehensive understanding of student performance.- The Z-score provides context on how a student's score compares to the mean of the group, while the absolute Z-score focuses on the size of the deviation without regard to direction.This structured data allows educators to analyze student performance comprehensively and identify patterns or outliers in academic achievements.
