Answer
Explanation:
Step1: Count occurrences of 'R'
Count the number of 'R's in the data. There are 6 'R's. So the frequency of 'R' is 6. The relative - frequency of 'R' is calculated as $\frac{6}{20}=0.3$.
Step2: Count occurrences of 'D'
Count the number of 'D's in the data. There are 8 'D's. So the frequency of 'D' is 8. The relative - frequency of 'D' is calculated as $\frac{8}{20}=0.4$.
Step3: Count occurrences of 'G'
Count the number of 'G's in the data. There are 2 'G's. So the frequency of 'G' is 2. The relative - frequency of 'G' is calculated as $\frac{2}{20}=0.1$.
Step4: Count occurrences of 'I'
Count the number of 'I's in the data. There are 4 'I's. So the frequency of 'I' is 4. The relative - frequency of 'I' is calculated as $\frac{4}{20}=0.2$.
Answer:
| Value | Frequency | Relative Frequency |
|---|---|---|
| R | 6 | 0.3 |
| D | 8 | 0.4 |
| G | 2 | 0.1 |
| I | 4 | 0.2 |
