Frequency Distribution Class Boundaries. We use the following steps to calculate the class boundaries in a frequency distribution. Subtract the upper class limit for the first class from the lower class limit for the second class. Rules for classifying scores into what is called a frequency distribution may be laid down as follows. The lower class boundary is found by subtracting 05 units from the lower class limit and the upper class boundary is found by adding 05 units to the upper class limit.
We use the following steps to calculate the class boundaries in a frequency distribution. The boundaries have one more decimal place than the raw data and therefore do not appear in the data. Subtract the upper class limit for the first class from the lower class limit for the second class. In a frequency distribution class boundaries are the values that separate the classes. We use the following steps to calculate the class boundaries in a frequency distribution. Each of the entries that are made in the table are based on the count or frequency of occurrences of the.
So applying same to all the mid points we get class intervals as 15-25 25-35 35-45 45-55 and 55-65.
Class Limits Class Boundaries Frequency 10 14 95 145 2 15 19 145 195 3 20 24 195 245 5 25 29 245 295 7 30 34 295 345 1. So applying same to all the mid points we get class intervals as 15-25 25-35 35-45 45-55 and 55-65. We use the following steps to calculate the class boundaries in a frequency distribution. This we get by subtracting and adding 5 Half of the interval. These principles of classifying data into groups is called frequency distribution. Each class is constructed using a single data value for each class eg 0 1 2 3 10 Class boundaries will be defined to separate the classes.
