Given below is a frequency distribution table. Read it and answer the question that follow: Class Interval Frequency 10 - 20 5 20 - 30 10 30 - 40 4 40 - 50 15 50 - 60 12 Which interval has a frequency of 10 ?

The given frequency distribution table is: Class Interval Frequency 10 - 20 5 20 - 30 10 30 - 40 4 40 - 50 15 50 - 60 12 Class interval = upper-class limit - lower class limit. In statistics, the data is arranged into different classes and the width of such classes is called a class interval. Class intervals in a particular distribution are generally equal in width but this might not be the case always. The frequency of a class interval is the number of observations that occur in a particular predefined interval. Therefore, from the frequency distribution table, we observe that the interval 20 - 30 has a frequency of 10 .

The frequency of a class interval is the number of observations that occur in a particular predefined interval. Therefore, from the frequency distribution table, we observe that the interval 30 - 40 has the lowest frequency 4 . Therefore, the required class with the lowest frequency is 30 - 40 .
