Hany Elbardesy explaining statistics for orthopaedics - part 1.
The speaker thanks everyone for joining and introduces the topic of research methodology and statistics in orthopedics.
- Data is the first step in research and can be numerical or categorical.
- Data is commonly distributed in a bell-shaped curve, known as the Gaussian distribution, but may be skewed to the left or right.
- Measures of central tendency, such as the mode, median, and mean, can be used to analyze data.
- The variance and standard deviation of the data can be calculated, and the size of the sample affects the width of the confidence interval. The speaker also mentions null hypothesis and types of errors.
