# Medical Statistics Basic Concepts - 1 day course

The course is sub-divided into the following Lessons:

1. Basic Statistical Concepts
2. Descriptive Statistics
3. Descriptive Graphs
4. Inference Statistical Concepts

## Basic Statistical Concepts

In this lesson, you will be introduced to the role of statistics; expose you to the common statistical symbols that you may come across when reading literature and demonstrate the importance of knowing the type or levels of data measurement.

In this lesson, you will cover the following topics:

• The Role of Statistics
• Statistical Symbols
• Data Types

## Descriptive Statistics

In this lesson, you will be introduced to descriptive statistics. Descriptive statistics deals with summarising data as briefly and as accurately as possible by the use of averages, standard deviation, range, minimum, maximum, percentiles, ratio, and percentages.

In this lesson, you will cover the following topics:

•  Percentage
• Ratio
• The Central Tendency: Mean, Median and Mode
• Dispersion: Range, Percentile, Variance, Standard Deviation, Standard Error.

## Descriptive Graphs

In this lesson, you will be introduce to graphical statistical tools. You will explore different types of graphs and observe when to use them. A selection of descriptive graphs to explore are: bar charts, pie charts, histograms, box plots, error bars, box-and-whisker plots and scatter plots.

In this lesson, you will cover the following topics:

• Bar chart
• Pie chart
• Histogram
• Box-and-whisker plot
• Error Bar
• Scatter plot
• ROC Curve

## Inferential Statistical Concepts

This lesson will introduce you to inference statistics. You draw inference about a population parameter based on parameter from a sample taken from the population. There are so many inferential tests and techniques available.

In this lesson, you will cover the following topics:

• The Normal Distribution
• Skewness and Kurtosis Distributions
• Probability
• Confidence Interval, Confidence Level, and Margin of Error
• Hypotheses
• The tail of the hypothesis: 1-tail and 2-tail
• Hypothesis or Significance Testing
• Degrees of Freedom
• Type I and Type II Errors
• Power of the Test
• Power and Sample Size Calculation.
