A relationship between two kinds of data is best represented by ------graph

Example: If a student Vishnu scored 45/50 on exam-1, 92/100 on exam-2 and 55.5/100 on the exam-3, the complete list of data looks like 105, 82, 94.5, 72.5, 92, 91, 52, 86, 100, 96, 98, 109, 96, 90, 92, 55.5 which is the 16 data points Vishnu uses for this project. IMPORTANT: Assume that the complete list of 16 scores as scores of 16 different students in a class and answer the questions below. Q1. What is the sample size of your data? Qualitative Quantitative Neither Discrete Continuous Neither Nominal Ordinal Interval Ratio Q2. Is the data of scores qualitative or quantitative? Q3. Is the data of scores discrete or continuous? Q4. What is the level of measurement for this data?
