The survey contains both the end user and ministry of interior and the respondents were 456 for end user and 582 for Ministry of interior. The analysis of the questionnaire has been done through the t-test statistics. If the results are greater than the tabulated values, then the data is found to be significant otherwise not. Chi - square test is also used for ordinal scales measurement in the questionnaires.

The independent t-test measures the difference between two groups keeping one similarity between them which certainly gives a good comparison of the data. Not all the questions have been included in the analysis, only important questions that are the part of both the questionnaires have been included to analyze the comparison between the data of both the questionnaires. Few extra questions that were not the part of these questionnaires were also included to include self importance of different questionnaires study.

Using t-test statistic (one sample t-test)

The one sample t test is used to test whether the sample mean (x) for a specific variable is "likely" or "unlikely" against the hypothesis that this average from a sample that was drawn at random from a population which we know the mean (µ), but not the standard deviation. In this case, the sampling distribution of means no longer follows the shape of the normal distribution. In fact, when we do not know all the population parameters (mean and standard deviation real), we can use the t distribution, akin to the normal distribution, and test whether a sample from a population with known mean but a standard deviation that is not.

One might think that the standard deviation obtained with the sample is a good estimator of the true value populational, but this is not the case, especially with a small sample size. Like the mean, standard deviation and variance of a sample varies from sample to sample ...
