--------------------------------------

Discusses basic concepts and techniques of Descriptive and Inferential statistics including Sampling methods, Probability, statistical theoretical Distributions

(z-dist(normal), t-dist, chi-square dist), tables and graphs, Sampling distribution of sample statistics, Central Limit Theory(CLT), Hypothesis testing, Confidence Interval(CI) estimation, Correlation and Regression. Math -227 is an introduction to Probability,Counting methods, measures of Central Tendency and Dispersion, Descriptive and Inferential statistics, Sampling distribution, Estimation of population parameters(Confidence Level(CL),Margin of Error, Critical value, Standard error,Sample size n), and Hypothesis Tests(Null and Alternative Hyp, Type 1 error, Type 2 error,Critical value-Test Statistics comparison method, P-value method).

Analysis of Variance(ANOVA Relationship Hyp test,

Categorical vs Categorical two data sets,

F-test statistic=Variance between over Variance within groups (SSE/d.f betw)/SSE/d.f within= MSE btw/MSE/within), Chi-square and student t-distributions, Linear correlation(Numerical vs Numerical two data sets, and Regression Analysis are also presented as topics.
