Objectives:
Collecting and analyzing various statistical data.
1# Time of Data Collection:
I have collected data from 15th June to 25th June, 2012
2#Way of collecting Data:
Though I do job in a private company & always too much busy with my work, I did the survey myself. On my holiday I went to the house/ work place of my known people & made the questionnaire filled.
3# Selection of Respondents:
I tried to select respondents from different type of private Job like Bank, financial organization etc. I selected them who are close to me so that I can get correct information from them on time.
4# Description of Respondents:
Most of the respondents are: a) Between 25-28 years of age b) Having educational experience ranging from BBA to MBA c) Six of them are Male and four of them are Female.
d) Most of them are employess, one is
buniessman and one is housewife
5# Difficulty in Collecting Data:
Some of my respondent wanted clarification about some related issues and I personally explained the fact. Most of the female respondents tried to deny to
disclose their age & some male their salary. But I was able to convince them and collected data successfully.
6# Problem/Limitation of the Questionnaire/Instrument
The questionnaire is too large and to some extent, it is complex and difficult to understand for general people.
7# Way of Improvement :
The information is sufficient to collect data from people around. The information is sufficient in accordance with the business environment of our country. The questionnaires have been found helpful to collect and analyze data.
However, the following steps can be taken:
a) The questionnaire can be made both in English & Bengali
b) The questionnaire can be much more simple and small.

10# Possibility of using Internet by More than 6 Respondents
Here,
No. of Respondents, n= 10
Internet Users, x= 8
So, success rate, r= x/n=8/10=0.8
Mean= n*P=10*0.8=8
We know that----
P(X = r) = n!(n-r)!r! . pr . qn-r
So, P(x=7) =0.2013
P(x=8) =0.3019
P(x=9) =0.2684
P(x=10)=0.1073
So, P(x>6)= P(x=7)+P(x=8)+P(x=9)+P(x=10)
=0.2013+0.3019+0.2684+0.1073
=0.8789 or, 87.89%
