Question

We know that formula of finding mode of grouped data is

Mode = l+(f1−f0)/(2f1−f0−f2)x h

Where, f0 is frequency of the class preceding the modal class and f2 is frequency of the class succeeding the modal class. But how to calculate mode when there is no class preceding or succeeding the modal class.​

Answer 1

Answer:

In the formula for mode of a grouped data, mode =l+{2f2−f0−f2f1−f0}×h, where symbols have their usual meaning f0 represents Frequency of the class preceding the modal class

where f= Frequency, l= Lowest value of the modal range, f1= Frequency of modal class, 

f2= Frequency of class succeeding the modal class and f0= Frequency of class preceding the modal class.

Hence, option C is correct.

Answer 2

Chlorophyll is any of several related green pigments found in the mesosomes of cyanobacteria and in the chloroplasts of algae and plants. Its name is derived from the Greek words χλωρός, khloros and φύλλον, phyllon. Chlorophyll is essential in photosynthesis, allowing plants to absorb energy from light
