Study Notes
Flower Data Analysis Statements
- All setosa flowers have shorter sepal lengths than versicolor flowers is not necessarily true; there are overlaps in measurements.
- All virginica flowers typically have larger sepal lengths than setosa flowers, a common characteristic observed in datasets.
- More than 75% of virginica flowers tend to have sepal lengths larger than the largest setosa flower, indicating a significant gap in size.
- More than 50% of setosa flowers do not have larger sepal lengths than the shortest versicolor flower as these groups have overlapping dimensions.
- Data collection may vary, and it's unclear if more data was collected on versicolor than on virginica without explicit dataset information.
- More data does not automatically imply a larger sample for setosa compared to virginica; both must be validated by examining actual counts in the datasets.
