Background Information:
This assignment pertains to statistical analysis for a given data sample. In statistics, a collection of data values is usually referred to as a distribution. A primary purpose of statistical analysis is to find ways to compress the complete set of data into summary statistics,that express properties of the distribution as a whole.Mean:The most common statistical measure is the mean, which is simply the traditional average. For the distribution x1, x2, … xn, the mean is usually represented by the symbol x Standard Deviation:Another common statistical measure is the standard deviation, which provides an indication of how much the individual values in the distribution differ from the mean. To calculate the standard deviation whose elements are x1, x2, … xn you need to perform the following steps:a. Calculate the mean of the distribution.
b. Go through the individual data items in the distribution and calculate the square of the difference between each data value and the mean. Add all these values to a running total.c. Take the total from step b and divide it by the number of data items.
d. Calculate the square root of the resulting quantity, which represents the standard deviation.In mathematical form, the standard deviation () is given by the following formula: = nx xnii 
12Histogram:
A histogram gives us a pictorial view of the data. Basically it is a frequency plot. For example given a histogram of a set of scores of students in a class, we can immediately see whether there were more students in the range 50-54 or 80-84 and so on. To draw a histogram, first decide upon the intervals. Let us say the interval is 5. Then count the number of students getting marks in the intervals 0-4, 5-9, 10-14, 15-19, 20-24, 25-29 and so on. The last interval will contain a single integer. Now you are ready to draw the histogram or the frequency plot. Here is an example of a histogram plot:0– 4|****************5- 9|***********************10-14|******************************15-19|*************************************20-24|**********************25-29|*************30-34|*********35-39|****40-44|**45-49|*50|**
