Statistics is a mathematical science concerned with the collection, presentation, analysis, interpretation or explanation of data. Sample- A sample is a subset of the units in a population. The most fundamental branch of statistics is descrip- tive statistics,that is, statistics used to summarize or describe a set of observations. Announcements We will ﬁnish the material in the ﬁrst lecture notes at a later point in the semester. Population- A population is a collection of objects (often called units or subjects) of interest. Need homework and test-taking help in Statistics? Linear Regression as a Statistical Model 5. 5 BASIC STATISTICS CONCEPTS EVERY DATA SCIENTIST NEEDS TO KNOW! Text Book : Basic Concepts and Methodology for Set, population, sample, Frequency and relative frequency , Data analysis, Presentation of Group data, Graphical Representation of Grouped Data. Statistics is the area of study dealing with the collection, presentation, analysis of data as well as drawing of meaningful conclusions from the data. The first quartile is essentially the 25th percentile; i.e 25% of the points in the data fall below that value. Basic Statistical Concepts. Statistics for Research Projects Chapter 1 Weâll start with a motivating example of how powerful statistics can be when theyâre used properly, and then dive into de nitions of basic statistical concepts, exploratory analysis methods, and an overview of some commonly used probability distributions. Descriptive statistics is encountered daily in the news media. Looks like youâve clipped this slide to  already. Statistical data, Descriptive Statistics Sample data may be summarized graphically or with summary statistics.  Some Basic concepts Statistics is a field of study concerned with 1- collection, organization, summarization and analysis of data. LECTURE NOTES #1 Reading assignment Review MD chs 1&2 or G chs 1-5. Descriptive statistics explain the basic concepts used to describe data.
