# 30203 Introduction to Statistics and Probability for Science Students 1

**Credits**: 3 intermediate credits in Mathematics

**Prerequisites**: none

**Authors**: Shmuel Zamir, Ruth Beyth-Marom

The course acquaints students with basic methods of data representation and with rudimentary concepts and tools of probability theory, two of the basic components of statistics. It provides a foundation for **Statistical Inference** (30204). The approach is mathematical; however, high-school level Mathematics is sufficient as background.2

**Topics**: **Introduction to statistics** historical development; the work of the statistician; **Fundamentals of descriptive statistics** grouping data in tables and graphs; measures of central tendency (mean, mode, midrange, median); measures of variation (percentage error, range and maximum deviation, interquartile range, mean absolute deviation and mean squared deviation, variance and standard deviation); percentile and standard score; Pearson's correlation coefficient; **Foundations of probability theory** basic set theory; probability space and probability function; uniform probability space and combinatorics; conditional probability; independent events; the complete probability formula; Bayes formula; **Discrete random variables** probability function and cumulative probability function; special distributions uniform, binomial, geometric, Poisson; expectation and variance; **Two dimensional random variables** and **continuous random variables** joint probability and marginal probability; dependent/independent random variables; uncorrelated random variables; probability density functions and cumulative probability functions of continuous random variables; uniform distribution and normal distribution.

2Students who studied high school Mathematics at the low, 3-point matriculation level, and those who studied Mathematics at the higher 4 or 5-point level, but have not reviewed the material for a long time or whose matriculation achievements were low, are advised to take the **Mathematics Refresher Workshop for Social Science Students** (95001) before taking this course.
