(1) Mean or Average:
Mean in theory is defined as the sum of all the elements of a set divided by the number of elements. We can get a fairly good idea about the whole set of data by calculating its mean. Thus the formula for mean is:
Mean = Sumofallthesetelements/Numberofelements
The importance of mean lies in its ability to represent the whole dataset with a single value.
(2) Median:
Median is the middle value of a dataset. So, if a set consists of an odd number of values, then the middle value will be the median of the set. On the other hand, if the set consists of an even number of sets, then the median will be the average of the two middle values.
Thus, the median may be used to separate a set of data into two parts. To find the median of a set, we need to arrange the elements of the set in increasing order. Then find the middle value.
(3) Mode:
The mode in a dataset is the value that is most frequent in the dataset. The mode also summarizes the gdataset with single information.
(4) Variance:
We may want to measure the deviation of a set of data from their mean value. The variance of the particular dataset will always be positive. Variance is used in the calculation of Standard Deviation, which is a very important concept of statistics.
(5) Standard Deviation:
The standard deviation is defined as the square rooting of the variance of the data.

The changing role of state is reflected in the eighth five year plan which mentioned that the planning in India will be indicative increasingly. In order to give some correctness to the changing role of state the eighth five year plan has identified the principles governing public sector. These are :
1. The public sector must withdraw from the areas where no public sector is served by its presence.
2. State should make investments only in those areas where investment is of main infrastructural nature where private sector is not likely to come forth to an adequate extent within a reasonable time perspective.
After that we saw a major shift in the Indian economy and the role of state has been changing from a controller, regulator and participator to that of a facilitator, observer and guide. The changes that took place in the role of state since 1991 are as under:
Overall, we can say that the role of state has changed from producer to production facilitator.
