Basic data analysis -- QA276.18 .C66 1992 PT.1

The first segment in a five part introductory video statistics course. Evaluating television ratings, tracking lightning strikes, and comparing salaries of men and women are introduced to describe how data can be measured and analyzed. The concepts of mean, median, outliers, and standard deviation are used to group numbers into meaningful categories. Data is plotted on stemplots, histograms, and b

Data analysis for one variable -- QA276.18 .C66 1992 PT.2

The second segment in a five part introductory video statistics course. What steps must be followed to measure one variable, such as a batting average, the emissions of an engine or the growth of a child? Concepts of normal curves, normal calculations, and straight-line and exponential growth are introduced as tools to predict the effect of a single variable, or the growth of a variable over time.

Data analysis for two variables -- QA276.18 .C66 1992 PT.3

The third segment in a five part introductory video statistics course. How do we compare the relationship between two things: Weight loss and metabolism, genetics and personality, or pollution and marine life? Here a new picture emerges, a scatterplot, that shows a graphic comparison of two variables. Fitting lines to data and correlation coefficients provide a numerical representation of how one

Planning data collection -- QA276.18 .C66 1992 PT.4

The fouth segment in a five part introductory video statistics course. If an individual wanted to prove a relationship between two things, where would they begin? Does aspirin prevent heart attacks? Does smoking cause cancer? How can one discover how Americans feel about a particular issue? The concepts of population, sampling versus census, survey and sample design and sampling distribution are i

Introduction to inference -- QA276.18 .C66 1992 PT.5

The fifth segment in a five part introductory video statistics course. Once a statistical experiment yields results, these results have to be qualified. Battery makers test a sample of their product to estimate how long each battery will last. Confidence intervals are introduced to determine how accurate that estimate is. Does coaching for the Scholastic Aptitude Test make a difference? Significan
