Learning and teaching strategies:
Aims:
This course introduces students to the basic concepts and logic of statistical reasoning and gives the
students introductory-level practical ability to choose, generate, and properly interpret appropriate
descriptive and inferential methods. In addition, the course helps students gain an appreciation for
the diverse applications of statistics and its relevance to their lives and fields of study. The course
assume that the students have some prior knowledge in statistics and its only prerequisite is basic
algebra.
apply and interpret correlation and modeling techniques for bivariate data in context of simple
linear models
so,
1. Statistical literacy is being able to read and use basic statistical language and graphical

representations to understand statistical information in the media and in daily life.
2. Statistical reasoning is being able to reason about and connect different statistical concepts
and ideas, such as knowing how and why outliers affect statistical measures of center and
variability.
3. Statistical thinking is the type of thinking used by statisticians when they encounter a statistical
problem. This involves thinking about the nature and quality of the data and, where the data
came from, choosing appropriate analyses and models, and interpreting the results in the
context of the problem and given the constraints of the data.
Learning Outcomes:
After successfully completion of the course students should be able to demonstrate:
1. Define statistics and how they lead to better business decisions
2. Analyze different types of data, apply appropriate statistical techniques to organize, summarize
and display data in a meaningful way.
3. Compute various measures of center, variation and location of data
4. Apply some basic probability rules
5. Understand the concepts of probability distributions and random variables then apply these
concepts to real life situations and evaluate the conclusions
6. Use appropriate probability distribution to estimate and perform a hypothesis testing about
parameters of one population
7. estimate and perform hypothesis testing of a mean of a population
8. Perform and interpret a linear correlation and regression to analyze the relationships in bivariate
data
