Question

how to find h in step deviation method

Answer 1

hlo dear.....
'h' is the difference between the class intervals...in the above case it is 5 and so in other ques...
Hope it helps u...if u liked the ans then pls mark it as brainliest☺☺☺

Answer 2

Answer:

Step-by-step explanation:

Step 1: Mean

Mean is an arithmetic measure of a given data set that can be determined by dividing the sum of all data points by the number of data points in a given data set. In a data set, the average point of all the data points we have in the set.

Depending on the size of the data, there are three ways to find the meaning of data collected, such as

Direct Method

Assumed Mean Method

Step-deviation Method

Step-deviation Method

If the data values ​​are large, a step deviation method is used to obtain the definition. The formula is provided by:

Mean

Here, assumed mean

frequency of ith class

deviation of ith class

Total number of observations

class mark

Step 2: Example

Find the mean of the following data set.

Therefore, the mean of the given data set is

Steps to be followed while applying the step deviation method are given below,

Create a table containing five columns as given below,

Column 1- Class interval.

Column 2- Classmarks (corresponding), denoted by x

i

. Take the central value from the class marks as the Assumed Mean and denote it as A.

Column 3- Calculate the corresponding deviations given as, i.e. di = x

i

- A

Column 4- Calculate the values of u

i

using the formula, u

i

= d

i

/h, where h is the class width.

Column 5- Frequencies (fi) (corresponding)

Find the Mean of u

i

= ∑x

i

u

i

/ ∑u

i

Finally, calculate the Mean by adding the assumed mean A to the product of class width(h) with mean of u

i
