**boundary**of each

**class**is calculated by subtracting half of the gap value 12=0.5 1 2 = 0.5 from the

**class**lower limit. On the other hand, the upper

**boundary**of each

**class**is calculated by adding half of the gap value 12=0.5 1 2 = 0.5 to the

**class**upper limit. Simplify the lower and upper

**boundaries**columns.

Keeping this in consideration, how do you find lower boundaries?

The **lower** class **boundary** is found by subtracting 0.5 units from the **lower** class limit and the upper class **boundary** is found by adding 0.5 units to the upper class limit. The difference between the upper and **lower boundaries** of any class.

Secondly, does the frequency distribution appear to have a normal distribution? No, the **distribution does** not **appear** to be **normal**. **Does the frequency distribution appear to have a normal**? **distribution**? Explain. Yes, because the **frequencies** start? low, proceed to one or two high? **frequencies**, then decrease to a low? **frequency**, and the **distribution** is approximately symmetric.

Thereof, how do you find the frequency distribution?

**Steps to Making Your Frequency Distribution**

- Step 1: Calculate the range of the data set.
- Step 2: Divide the range by the number of groups you want and then round up.
- Step 3: Use the class width to create your groups.
- Step 4: Find the frequency for each group.

How do you find the class frequency?

Count the tally marks to **determine** the **frequency** of each **class**. The relative **frequency** of a data **class** is the percentage of data elements in that **class**. The relative **frequency** can be calculated using the formula fi=fn f i = f n , where f is the absolute **frequency** and n is the sum of all **frequencies**.
