Topics:
- Statistics
as a science: Definition. Basic statistical terminology. Populations
and samples. Parameters and statistics. The role of statistics in
experiment research.
- Descriptive
statistics: Statistical tables
and graphs. Histograms. Measures of central tendency (arithmetic
mean, median, mode). Measures of
variability (range, variance, standard deviation). Tchebysheff’s
Theorem and the empirical rule.
Coefficient of variation.
Percentiles and quartiles.
- Probability: Role of probability in statistics. Experiments and experimental
outcomes. Sample space, events,
union, intersection, and complements of events. Mutually exclusive events, independent
events, and conditional probability.
Additive and multiplicative rules.
- Probability
distributions of random variables: Experimental outcomes and random
variables. Discrete and continuous random variables. Discrete probability
distributions. Mathematical Expectation.
- Discrete
random variables: Binomial
distributions, mean, variance, use of binomial formula and probability
tables. Poisson distributions,
mean, variance, use of Poisson formula and probability tables. Applications.
- The
normal distribution: The
parameters of the normal distribution.
The standard normal distribution.
Tabulated areas under the standard normal curve. The standardization formula. Applications. The normal approximation to the
binomial.
- Sampling
Distributions: The central
limit theorem. Distribution of the
mean of a sample from a normal population. Large-sample sampling distributions of
sample means and proportion for one and two populations.
- Large-sample
estimator: Point and interval
estimation. Interpretation of these
estimators. Unbiased
estimators. Large-sample estimation
of means and proportions for one and two populations.
- Large-sample
tests of hypotheses: Large-sample
hypothesis testing for means
and proportions
for one and two populations. Observed significance levels.
