If you do well in this course, you will be able to:
The student, with the aid of text, computer, Internet connection, World Wide Web links and sites, calculator, quizzes, assignments, and research projects, should meet the following objectives:
- Be familiar with basic statistical terms such as discrete variable, continuous variable, statistical inference, population, sample, and sample distribution.
- Be able to round numbers to appropriate number of significant digits when performing calculations.
- Determine the mean, median, mode, and type of skewness for ungrouped data.
- Identify the modal class and median class of a frequency distribution; compute relative frequencies and percentiles.
- Compute measures of dispersion, including the range, variance, standard deviation, and the coefficient of variation.
- Know the basic probability concepts and apply the multiplication and addition rules of probability to business applications.
- Use the Normal, Poisson, and Binomial tables to solve business problems.
- Know how to use Chebyshev's Theorem for determining probabilities for any set of data.
- Compute and interpret coefficients of correlation (both Pearson and Spearman) and the coefficient of determination (R squared).
- Compute and interpret link and chain index numbers based on economic and business time-series data. Use price index numbers to determine real wages and constant-dollar balance sheets.
- Know the various types of acceptable sampling methods and the concept of sampling distributions and Central Limit Theorem.
Compute interval estimates (confidence intervals) for the population mean and proportion.
- Determine the required minimum sample sizes for interval estimates, given the acceptable accuracy and degree of confidence.
- Familiarize with the usage of computers and statistical packages to solve business problems.
