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:	The major objective of this course is to increase the student data analysis skills using different statistical tools, both from descriptive and inferential statistics.

BASIC CONCEPTS OF THE COURSE

1	An interval estimate of a parameter is an interval or a range of values used to estimate the parameter
2	A statistical hypothesis is a conjecture about a population parameter. This conjecture may or may not be true.
3	If two independent samples are selected from two normally distributed populations in which the population variances are equal (𝜎 1 2 = 𝜎 2 2) and if the sample variances s1 2 and s2 2 are compared as s1 2_2s2 , the sampling distribution of the variances is called the F distribution.
4	A scatter plot is a graph of the ordered pairs (x, y) of numbers consisting of the independent variable x and the dependent variable y
5	The population correlation coefficient denoted by the Greek letter 𝜌 is the correlation computed by using all possible pairs of data values (x, y) taken from a population
6	A multiple regression equation with two independent variables (x1 and x2)
7	The one-way analysis of variance test is used to test the equality of three or more means using sample variances.
8	The two-way ANOVA is an extension of the one-way analysis of variance; it involves two independent variables. The independent variables are also called factors.
9	The Spearman rank correlation coefficient is a nonparametric statistic that uses ranks to determine if there is a relationship between two variables.
10	The sign test for a single sample is a nonparametric test used to test the value of a population median.
