What is inclusive and exclusive OR?

What is inclusive and exclusive OR?

Inclusive OR allows both possibilities as well as either of them. So, if either A or B is True, or if both are True, then the statement value is True. Whereas Exclusive OR only allows one possibility. So if either A or B is true, then and only then is the value True.

What is exclusive method?

Exclusive Method– This method is used for those series in which the upper limit of one class becomes the lower limit of the next class. It is called as exclusive series because the frequencies of the upper limit of a class interval are not included in that particular class.

What is the upper class limit for the class 35 45?

Answer: The upper value of specific class interval is called the Upper limit of that class. And, the lower value of specific class interval is called the Lower limit of that class. Thus, the Upper Limit of Class Interval 35 – 45 is 45.

What is class mark?

The class midpoint (or class mark) is a specific point in the center of the bins (categories) in a frequency distribution table; It’s also the center of a bar in a histogram. It is defined as the average of the upper and lower class limits.

What is the class mark of modal class?

Answer: The modal class is the group with the highest frequency. So it will be the group corresponding to 17. Question: What is the modal class if the frequency number is 2, 1, 4, 3? Answer: The modal class is the group containing the highest frequency.

What is a modal class in math?

Modal means the one that occurs most often (averages: mode). In maths, the mode is one of the most common ways to describe a set of data. The modal class is, therefore, the group with the highest frequency. For example: if you counted the number of pencils in different pencil cases and you decided to group them.

How do you find the class 10 modal class?

Mode for grouped data is given as Mode=l+(f1−f02f1−f0−f2)×h , where l is the lower limit of modal class, h is the size of class interval, f1 is the frequency of the modal class, f0 is the frequency of the class preceding the modal class, and f2 is the frequency of the class succeeding the modal class.

How do you find the class mark of 80 90?

Now, coming to our question, we have been given the class interval as (80 – 90). So, we can find the class mark as 85. Therefore, the class mark of the class interval (80 – 90) is 85.

What is the class mark of the class 85 90?

To calculate the mean of a continuous series, mid points of the various class intervals is taken before calculating the mean which is also called the class mark. For example, if the class interval is 80-90 then before calculating the mean mid point that is the class mark is calculated which is 85.

What is the class mark of 70 80 class?

Therefore 75 is the class mark of interval. Therefore 75 is the class mark of interval. Aakash EduTech Pvt.
