In the context of frequency distributions, let's clarify the terms and identify the smallest numbers that can belong to each class:
1. **Lower Class Limit:** This is the smallest value that can be included in a class interval. The smallest lower class limit can be any real number or integer, depending on the context of the data. For example, if we have a class interval of \(0-10\), the lower class limit is \(0\).
2. **Upper Class Limit:** This is the largest value that can be included in a class interval. Similar to the lower class limit, the smallest upper class limit can also be any real number or integer. For example, in the same class interval of \(0-10\), the upper class limit is \(10\).
3. **Class Boundary:** Class boundaries are used to separate the classes without gaps. The class boundary is typically found by averaging the upper limit of one class and the lower limit of the next. The smallest class boundary typically depends on the class intervals. For instance, in the class intervals of \(0-10\) and \(10-20\), the class boundary between these two would be \(10\). However, a class boundary can also be determined similarly for lower intervals (e.g., if the interval is \(0-1\), the class boundary would be slightly lower than \(0\)).
4. **Outlier:** An outlier is a data point that lies outside the overall pattern of distribution. The smallest number that can be an outlier will depend on the data set. Generally, an outlier is defined based on specific statistical criteria (like being more than 1.5 times the interquartile range above the third quartile or below the first quartile). Thus, the smallest outlier can be less than any value in the data set, depending on the context.
In conclusion, while we can identify numerical values for lower and upper limits based on specific class intervals, class boundaries and outliers depend more on the data distribution and context rather than fixed numerical values.
