Course Description: Statistics II: The aim of the courses is that inference making in Business. The objective of the course is to help students to understand theoretical characteristics of statistical methods and develop practical knowledge and skills to analyze the business data.
Course Objectives: This course is specifically designed to provide knowledge related to intervals of confidence, hypothesis testing and regression analysis. At the end of the course, student should be able to understand the fundamentals of statistical inference.
BASIC CONCEPTS OF THE COURSE
1 confidence interval - a specific interval estimate of a parameter determined by using data obtained from a sample and the specific confidence level of the estimate
2 degrees of freedom - the number of values that are free to vary after a sample statistic has been computed; used when a distribution (such as the t distribution) consists of a family of curves
3 disordinal interaction- an interaction between variables in ANOVA, indicated when the graphs of the lines connecting the mean intersect
4 explanatory variable - a variable that is being manipulated by the researcher to see if it affects the outcome variable
5 independence test - a chi-square test used to test the independence of two variables when data are tabulated in table form in terms of frequencies
6 left-tailed test - a test used on a hypothesis when the critical region is on the left side of the distribution
7 parametric tests - statistical tests for population parameters such as means, variances, and proportions that involve assumptions about the populations from which the samples were selected
8 type I error - the error that occurs if you reject the null hypothesis when it is true
9 type II error - the error that occurs if you do not reject the null hypothesis when it is false
10 t distribution - a family of bell-shaped curves based on degrees of freedom, similar to the standard normal distribution with the exception that the variance is greater than 1; used when you are testing small samples and when the population standard deviation is unknown

CONCLUDING REMARKS BY THE COURSE LECTURER

Students are expected to have gained a comprehensive understanding of statistics. Meanwhile, students should work with real data from companies that operate in Albania in order to estimate regression equation, to interpret the results.
