STAT 200: Elementary Statistics Overview Materials Assessment Plan Prerequisites Online Notes About Credits 4 Statistics is the art and science of using sample data to make generalizations about populations. Students who successfully complete this could should be able to:A sample is defined as a set of selected individuals, items, or data taken from a population of interest. A characteristic (usually numeric) that describes a sample is referred to as a sample statistic. NOTE: Inferential statistics are used to help the researcher infer how well statistics in a sample reflect parameters in a population. DEFINITION

Label what you’re given: “ X normal with μ = 80 and σ = 5.”. Next, write what you need to find, using symbols: “Find P ( X < 90).”.Johann Carl Friedrich Gauss (1777–1855) Nationality: German.

Statistics and Probability as a strand is all about developing skills in collecting and organizing data using charts, tables, and graphs; understanding, analyzing and interpreting data; dealing with uncertainty; and making predictions about outcomes. The K to 10 Mathematics Curriculum provides a solid foundation for Mathematics at Grades 11 to 12.Examples of a population are all high school students, all cats, all scholastic aptitude test scores. A relatively small group of items selected from a population is a sample . If every member of the population has an equal chance of being selected for the sample, it is called a random sample . Examples of a sample areThe median is a better measure of the "center" than the mean because 49 of the values are 30,000 and one is 5,000,000. The 5,000,000 is an outlier. The 30,000 gives us a better sense of the middle of the data. Another measure of the center is the mode. The mode is the most frequent value.
