Question

formula of mean ,medium and mode from statistics​

Answer 1

HELLO

1. MEAN

The formula for the direct method is as follows:

Mean= ∑fX/∑f

Here, ∑fX= Summation of the product of values of items with their corresponding frequencies

∑f= Summation of all the frequencies.

2.MEDIAN

.If the value of N is odd then simply the value of (N+1)/2 th item is median for the data.

.If the value of N is even, then use this formula: Median = [ size of (N+1)/2 term + size of (N/2 + 1)th term]÷2

3.MODE

Mode = l + h [(f1-f0)/(2f1-f0-f2)]

Here, l= The lower limit of the modal class

f1 = Frequency corresponding to the modal class,

f2 = Frequency corresponding to the post-modal class,

and f0 = Frequency corresponding to the pre-modal class.

Answer:

radhe radhe

Step-by-step explanation:

1. mean = the arithmetical average of all observations in a given data is known as automatic mean or simply mean.

mean = the sum of all observations in the data / total number of observation.

2. median = the scores are arranging in ascending or descending order the number appearing exactly at the middle position in this order is known as median of the observation.

3. mode = the score which is repeated maximum number of times in the given data is known as the mode of number
