Introduction to Statistics
- The nature of data, uses and abuses of statistics, design of experiments statistics with calculator and computers.
Describing exploring and comparing data
- Summarizing data with frequency tables, pictures of data, measures of central tendency, measures of variation, measures of position, exploratory data analysis.
- Definitions, addition rule, multiplication rule, probabilities through simulation, counting.
- Random variables, binomial experiments, mean, variance and standard deviation for the Binomial distribution.
Normal Probability Distributions
- The Standard Normal distribution, non-standard Normal distributions, the Central Limit Theorem, Normal approximation to the Binomial distribution.
Estimates and Sample Sizes
- Estimating a population mean using large and small samples, estimating a population proportion.
- Fundamentals of Hypothesis Testing, testing a claim about a mean using large and small samples, testing a claim about a proportion.
- Confidence intervals.
Inferences from Two Samples
- Inferences about two means: dependent samples, inferences about two means: independent and large samples, inferences about two means: independent and small samples, inferences about two proportions
Correlation and Regression
- Correlation, regression variation
At the end of the course, the successful student should be able to:
- Define the terms “population” and “sample” as they apply to Statistics
- Define and differentiate between the nominal, ordinal, interval and ratio levels of measurement
- Explain the proper use of Statistics within real world application and provide examples of its abuse
- Have an understanding of experimental design and the use of random number tables and generators
- Create and interpret frequency tables, histograms, cumulative frequency tables, stem and leaf displays and scatter plots
- Calculate and interpret measures of central tendency and variation
- Calculate and interpret standard scores
- Understand the classical and relative frequency approaches to probability and employ counting techniques
- Know and apply the addition and multiplication rules for probability and the concept of conditional probability
- Be able to differentiate between discrete and continuous random variables
- Determine whether the conditions for a Binomial experiment apply and compute the Binomial probabilities
- Compute the mean, variance and standard deviation for the Binomial distribution
- Determine probabilities of standard and non-standard normal random variables
- Use the Normal distribution to approximate Binomial probabilities
- Understand and apply the Student t distribution
- Apply the Central Limit Theorem to estimate population parameters using large and small samples
- Apply the Central Limit Theorem to estimate the difference between population parameters
- Perform hypothesis tests on population parameters or the difference between population parameters using large and small samples
- Create confidence intervals for population parameters or their difference using large and small samples.
- Create Contingency Tables and perform goodness-of-fit testing in multinomial experiments using the Chi-square test. (optional)
- Understand and apply Chebychev’s theorem (optional)
- Understand and apply the Poisson and other probability distributions (optional)
Evaluation will be carried out in accordance with Douglas College policy. The instructor will present a written course outline with specific evaluation criteria at the beginning of the semester. Evaluation will be based on some of the following:
