CHAPTER IV
FINDINGS AND CONCURRENT DISCUSSIONS
Hypothesis 1: People are resistant to the technological change in the security system of the organization.
Hypothesis 2: Lack of proper security system results in organizationally important information hacked and misused.
Hypothesis 3: A proper security system in any organization increases data security and in turn efficiency and productivity of the organization.
Hypothesis 4: Proper identification system reduces absenteeism

Types of Data:
The random variables are of two types and two types of data are generated out of them:
a) numerical and b) categorical
A chi square (X2) statistic is used in order to study whether the categorical variables differ from one another or not. The categorical variable generates data in the categories and numerical variable generates data in numerical form.
For example, if it is asked - "What is your specialization?" or Do you own a bike?" are categorical type as they give data such as "computers" or "yes.", whereas questions like
"What marks did you get?" or "What is your age?" are numerical type.
It is very clear that the numerical data is basically of two types: 1) continuous, 2) discrete.
To understand the differences between the types of numerical variables.
Data Type Question Type Possible
Responses
Categorical What is your marital status? Married or unmarried
Numerical(Discrete) Number of bikes that you
own? 2 or 3
Numerical(Continuous) What’s your height? 5’11”

- the Chi Square statistic compares the tallies or counts of categorical responses between two (or more) independent groups.
- the Chi square tests are used only on actual numbers and not on percentages, proportions, or means.
For example,
A case of a medicine trial conducted on different animals. The hypothesis in this case was set that the animals consuming the drug shows increase in the heartbeat as compared to animals who did not consume the medicine.
On conducting the study, researcher collected the following data:
H0: The proportion of animals whose heartbeat increased is independent of medicine consumption..
H1: The proportion of animals whose heartbeat increased is associated with medicine treatment.

No Heartbeat

Not treated 50 35 85
Total 106 59 165

Applying the formula above we get:
Chi square = 165[(56)(35) - (24)(50)]2/ (80)(85)(59)(106) = 2.818
The degree of freedom is very important before proceeding ahead. When a comparison is made between one sample and another,
the degrees of freedom= (number of columns minus one) x (number of rows minus one) Thus, degree of freedom = (2-1) x (2-1) = 1.
Now, the chi square statistic (x2= 2.818), alpha level of significance (0.05), and degrees of freedom (df = 1).
From the data collected the Chi square distribution table has 1 degree of freedom and the value of x2(2.818) lies between 2.706 and 3.841. Thus we can see that the corresponding probability is between the 0.10 and 0.05 probability levels which means the p-value is above 0.05. As the p-value> conventionally accepted significance level of 0.05 this proves that we accept the null hypothesis.
Now if the new x2value is 4.125 and this value exceeds the table value of 3.841 (at 1 degree of freedom and an alpha level of 0.05).
This means that p is less than the 0.05, so the alternative hypothesis is accepted.

Table value for X2for 1 degree of freedom at 5% significance level = 3.841
Conclusion:
Calculated value of Chi Square [0.01486] is less than the table value [3.841]. So we accept the null hypothesis and conclude that technological change in the security system of the organization and people resistance towards change are independent. That is people are not resistance to the technological change in the security system of the organization.

Conclusion:
Calculated value of Chi Square [6.32534] is greater than the table value [5.991]. So we reject the null hypothesis and conclude that security system and information hacking are dependent. I.e. if the security system is very strong information hacking is not possible. If there is a flaw in the security system the information can be easily hacked and it can be misused against the organization.
