A parameter is a numerical description of a population characteristic. a statistic is a numerical description of a sample characteristic. work step by step data sets all have characteristics and usually we would like to investigate a specific characteristic.

This introductory course is for sas software users who perform statistical analyses using sas/stat software. the focus is on t tests, anova, and linear regression, and includes a brief introduction to logistic regression. this course (or equivalent knowledge) is a prerequisite to many of the courses in the statistical analysis curriculum. Introduction to chapter1 statistics learning objectives after reading this chapter, you should be able to: 1 distinguish between descriptive and inferential statistics. 2 explain how samples and populations, as well as a sample statistic and population parameter, differ.

Numerical descriptive measures computed from data are called statistics. numerical descriptive measures of the population are called parameters. inferential statistics can be used to generalize the findings from sample data to a broader population. completing this unit should take you approximately 22 hours. And maybe that guy would come and say, well, you know, actually, the probability that i get a 1 is 1/6 plus 0.001 and the probability that i get a 2 is 1/6 minus 0.005. and there would be some fluctuations around this. Introductory statistics follows scope and sequence requirements of a one semester introduction to statistics course and is geared toward students majoring in fields other than math or engineering. the text assumes some knowledge of intermediate algebra and focuses on statistics application over theory.

1. Introduction To Statistics
introduction to descriptive and inferential statistics the role of statistics the goal of virtually all quantitative research studies is to identify and describe relationships among constructs. data are collected in a very systematic manner and conclusions are drawn based on the data. Title: chapter 1: introduction to statistics 1 chapter 1 introduction to statistics 2 variables. a variable is a characteristic or condition that can change or take on different values. most research begins with a general question about the relationship between two variables for a specific group of individuals. 3 population. Chapter 1 descriptive statistics 1.1 descriptive vs. inferential there are two main branches of statistics: descriptive and inferential. descrip tive statistics is used to say something about a set of information that has been collected only. inferential statistics is used to make predictions or comparisons. Introduction to statistics. what is statistics? statistics is a mathematical science including methods of collecting, organizing and analyzing data in such a way that meaningful conclusions can be drawn from them. in general, its investigations and analyses fall into two broad categories called descriptive and inferential statistics. Statistics include numerical facts and figures, but also involves math and relies upon calculations of numbers. it also relies heavily on how the numbers are chosen and how the statistics are interpreted. 1.2: importance of statistics it is important to properly evaluate data and claims that bombard us every day.
