STA2023 Statistics

Lectures are limited to main concepts and solving examples. Most of the time, we will be solving problems in class. In every class. 

The use of a graphing calculator is strongly recommended: Casio 9750, TI 84 or similar.


Taken from the "Insider s guide to teaching with the Triola Statistics Series" by Mario Triola, author of the textbook: The author s personal preference is to require that each student have a TI 83 plus or TI 84 plus calculator, and each student also do several software projects using Statdisk.

R code: > barplot(dbinom(x = 0:10, size = 10, prob = 0.5),names.arg = 0:10,space=0, main="Binomial dist histogram for n=10, p=.5")

Probability: The Deck of Cards.

A deck of cards consists of 4 suits, 13 cards each for a total of 52 cards. The four suits are: Spades, Hearts, Diamonds, and Clubs. Each suit contains an A (Ace), numbers from 2 to 10, and three face cards: J, The Jack; Q, the Queen and K, the King.
Colors: Hearts and Diamonds are red, Spades and Clubs are black.
