Yadulla Hasanli, Nazim Hajiyev, Gunay Rahimli:Distribution and Analysis of Admission
Scores (In the Case of Azerbaijan

The results of the model based on data show that over time the average score of
applicant across the country has increase each year by 1%. Applicants’ base average
score is 165.6 without considering trend factor. (exp(5.1093116842=165,6)

This result can be explained by the fact that the development of science and
technology, expanding the access of applicants to information and knowledge (e-
library, internet, mobile phones, etc.) positively influenced their scores on the
entrance exams and increased their average score.

Econometric evaulation of the dependence of the deviations from the mean score (σ-
standard deviation) from time. An econometric evaluation was made of the
dependence of the deviations from the mean score from time. For this, the following
specification of the regression equation was considered:

Standart_deviation=c(1)+ c(2) @TREND (4)

The result of the econometric evaluation of the regression equation in the EViews
application package was as follows:

STDEV_TOTAL = 120.706446091 + 2.37442438611*@TREND (5)

The main statistical characteristics of model (5), residiual diagnostics tests and other
relevant tests indicates that, the model is adequate. From model (5), it can be seen
that, if not to take into account the time trend, base value of the standard deviations
of scores is 120,7.

CONCLUSIONS
It was found that in any of the groups points scored by applicants and bachelors do not
have a normal or exponential distribution, that is, they are asymmetric. To assess the
level of asymmetry, an analysis was carried out with the calculation of the moment and
structural asymmetry coefficients and it was found that the distribution of points scored
on all specialty groups is asymmetric to the right. Also, on the basis of the time series,
an econometric evaluation was made of the dependence of the average scores obtained
by the applicants, as well as deviations from the mean score (σ-standard deviation) from
time. It was found that if not to take into account the time trend, then the basic average
score of applicants is 165.6, and the deviation from this score is 120.7. According to the
results of the model, it was found that with a time trend, the average score of applicants
each year increases by about 1%. We can explain this result by the fact that with the
development of science and technology, the opportunity for applicants to access
information databases (electronic libraries, Internet, mobile phones, etc.) has increased,
and this has a positive effect on the scores collected at the entrance exams and raises the
average score.
