Can you have a class width of 1?

Since the smallest value in the data set is 0.25, we choose 0.00 as the lower limit for the first class. The class width is 1 and the first lower class limit is 0.00, so the lower limit for the second class is 0.00 + 1 = 1.00….

Class Frequency Relative Frequency
5.00 – 5.99 1 0.015
6.00 – 6.99 2 0.031

How do you find the class boundary?

Use the following steps to calculate the class boundaries:

  1. Subtract the upper class limit for the first class from the lower class limit for the second class.
  2. Divide the result by two.
  3. Subtract the result from the lower class limit and add the result to the the upper class limit for each class.

What is the lower class boundary of 0 4 class?

-0.5 to 4.5
In the age class 0 – 4, the class limits 0 and 4 are actual data values. Age 4 represents the ages 3.5 to 4.5, including 3.5 and not including 4.5. (i.e. [3.5, 4.5)). Thus the class boundaries of 0 – 4 are actually -0.5 to 4.5.

What is the class boundary?

Class boundary is the midpoint of the upper class limit of one class and the lower class limit of the subsequent class. Each class thus has an upper and a lower class boundary.

What is a lower class boundary?

The lower class boundary of a given class is obtained by averaging the upper limit of the previous class and the lower limit of the given class. The upper class boundary of a given class is obtained by averaging the upper limit of the class and the lower limit of the next class. Class marks.

What is the lower class limit?

Example 1: Finding Class Limits in a Frequency Distribution The lower class limit is simply the smallest possible value in each class: Conversely, the upper class limit is the largest possible value in each class: What is this?

How do you find lower class boundaries?

The lower class boundary of a given class is obtained by averaging the upper limit of the previous class and the lower limit of the given class. The upper class boundary of a given class is obtained by averaging the upper limit of the class and the lower limit of the next class.

How do you calculate class size?

We also know that the class size is defined as the difference between the actual upper limit and actual lower of a given class interval. Therefore, the class size for the class interval 10-20 is 10.

What is the upper class boundary of the class 23 35?

The class interval (23-35) is given where 23 is the lower-class limit and 35 is the upper-class limit of the interval.

What is class boundary example?

Example A.

Class Frequency Class boundaries
180 – 199 2 179.5, 199.5
200 – 219 5 199.5, 219.5
220 – 239 12 219.5, 239.5
240 – 259 6 239.5, 259.5

How do you find the class boundary from mid value?

Detailed Solution

  1. Given: The mid value of the class interval = 42. Class size = 10.
  2. Concept used: Mid value of the class interval = (Upper limit + lower limit)/2. Class size = Upper limit – Lower limit.
  3. Calculation: Let the lower and upper limit be x and y respectively. ⇒ (x + y)/2 = 42. ⇒ x + y = 84. ⇒ x = 84 – y —- (1)
