Introdução à Estatística

Disciplina Bioestatística da pós-graduação em Engenharia Biomédica na UFABC

• Professor: Marcos Duarte
• De 6 de junho a 22 de agosto de 2018, quartas-feiras das 17h às 21h, São Bernardo do Campo

Esta disciplina é baseada em dois cursos MOOC gratuitos disponíveis na internet (os quais eu não tenho nenhuma participação):

1. Intro to Descriptive Statistics (review)
2. Intro to Inferential Statistics (review)

Esta disciplina acompanhará o conteúdo destes dois cursos online. As aulas presenciais serão basicamente aulas para tirar dúvidas. Os cursos online são ministrados em inglês, mas há legendas em português para os vídeos, e há material de apoio e fórum.

Intro to Descriptive Statistics (videos, lessons, forum)

• Intro to Research Methods
  Introduction to several statistical study methods and the positives and negatives of each.
• Visualizing Data
  How to take data and display it to the world. How to create and interpret histograms, bar charts, and frequency plots.
• Central Tendency
  How to compute and interpret the 3 measures of center for distributions: the mean, median, and mode.
• Variability
  How to quantify the spread of data using the range and standard deviation. How to identify outliers in data sets using the concept of the interquartile range.
• Standardizing
  How to convert distributions into the standard normal distribution using the Z-score. How to compute proportions using standardized distributions.
• Normal Distribution
  How to use normalized distributions to compute probabilities. How to use the Z-table to look up the proportions of observations above, below, or in between values.
• Sampling Distributions
  How to apply the concepts of probability and normalization to sample data sets.

Intro to Inferential Statistics (videos, lessons, forum)

• Estimation
  How to estimate population parameters from sample statistics using confidence intervals and estimating the effect of a treatment
• Hypothesis Testing
  How to use critical values to make decisions on whether or not a treatment has changed the value of a population parameter
• t-tests
  How to test the effect of a treatment or compare the difference in means for two groups when we have small sample sizes
• ANOVA
  How to test whether or not there are differences between three or more groups
• Correlation
  How to describe and test the strength of a relationship between two variables
• Regression
  How to describe the way in which changes in one variable are related to changes in a second variable
• Chi-squared Tests
  How to compare and test frequencies for categorical data.
