Heya guys ❤
Good morning
Can you explain me about the inclusive frequency and exclusive frequency.
please no irrelevant answers.....
Please don't answer if you don't know....I have exams tomorrow....!
Answers
Each class interval has two limits viz lower class limit and upper class limit. When developing a frequency distribution one usually looks at the type of variable -- discrete or continuous. When both lower and upper limits of class intervals are included then it is called an inclusive class interval and it is concerned with the data of a discrete variable which are isolated values. For example, 5-10, 11-16, 17-22 ..... are the inclusive class intervals of a discrete variable. On the contrary, when lower class limit is included but upper limit is excluded it is an exclusive class interval which is concerned with continuous variable. For example, 10.5-15.5, 15.5-20.5, 20.5-25.5 ...... are exclusive class intervals of a continuous variable. Here, the lower class limit 10.5 is included in the class-interval 10.5-15.5 but not the upper class limit i.e. a value 10.5 will be included in the class 10.5-15.5 while a value 15.5 will be included in next class 15.5-20.5 but excluded from the class 10.5-15.5.
Hope this clarifies.
GROUPED FREQUENCY DISTRIBUTION TABLE - EXAMPLE
Marks of 20 students in Maths out of 25 are
12,15,15,17,17,17,19,19,19,19,19,21,21,21,23,23,23,23,25,25.
Marks Number of Students
0−10 0
10−20 11
20−30 9
DEFINE AND IDENTIFY RANGE OF DATA - EXAMPLE
From the data 2.5.8.6.9.4.8.2.7
Highest value is=9
least value =2
range of data is =highest - least value=9-2=7
