## 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:

- Subtract the upper class limit for the first class from the lower class limit for the second class.
- Divide the result by two.
- 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

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