Frequency Formula

Find the relative frequencies

• 37%, 76%, 92%, 95%, 98%, 100%

• 28%, 30%, 12%, 2%, 2%, 2%

• 33%, 37%, 20%, 7%, 7%, 7%

• 37%, 39%, 16%, 3%, 3%, 3%

Find the cumulative frequencies.

• 28, 56, 84, 100

• 28, 58, 70, 72, 74, 76

• 33%, 37%, 20%, 7%, 7%, 7%

• 28, 30, 12, 2, 2, 2

What would be the cumulative frequency for the third class?

• 5

• 12

• 17

• 18

What is the formula for relative frequency?

• f*N

• f-N

• f/N

• (f+x)/N

In the given frequency distribution, what is the upper class boundary of the last interval?

What is f₁ stands for

• Frequency of the modal class

• Frequency of the class preceding the modal class

• Frequency of the class succeeding the modal class

• Cumulative frequency of the modal class

What is 'cf' represents in this formula

• Cumulative frequency

• Class interval

• Frequency

• Class frequency

In order to find mode of the data identify f_{0 ,} f_{1 ,} f₂

• f₀ = 15 , f₁ = 118 , f₂ = 142

• f₀ = 118 , f₁ = 142 , f₂ = 127

• f₀ = 15 , f₁ = 18 , f₂ = 118

• f₀ = 15 , f₁ = 118 , f₂ = 18

In order to find mode of the data identify f₁ and L

• f ₁ = 4 and L = 51

• f ₁ = 15 and L = 80

• f ₁ = 15 and L = 71

• f ₁ = 8 and L = 61

in this formula L stands for

• Length of the median class

• Lower boundary of the median class

• Last term of the median class

• Slant height of the median class
