What is the average petal length per group (one average only)? 2.What is the most frequent group in the data? 3. What is the median of petal width? 4. What is the range of sepal length in Iris Virginica group? 5. What is the variance and standard deviation of sepal length under iris setosa? 6. Which has higher total sepal width between iris versicolor and iris virginica? 7. In terms of average, which group has the biggest petals? 8. Which is more dispersed in in terms of sepal length between iris versicolor and iris setosa? 9. create a frequency distribution table with 4 classes for petal width. Use the minimum value as the first lower class limit. Include frequency and classmark only. 10. Find the grouped mean of item #9
