Descriptive Statistics
Definition Descriptive statistics involves summarizing and describing the basic features of a dataset.
Measures of Central Tendency Used to describe the middle value of a dataset.
- Mode: the value that appears most frequently in the dataset
- Median: the middle value in the dataset when it is arranged in order
- Mean: the average value of the dataset
Measures of Variability Used to describe the spread or dispersion of a dataset.
- Range: the difference between the largest and smallest values in the dataset
- Interquartile Range (IQR): the difference between the 75th percentile and the 25th percentile
- Variance: the average of the squared differences from the mean
- Standard Deviation (SD): the square root of the variance
Data Visualization Used to visually describe and summarize the dataset.
- Histograms: a graphical representation of the distribution of a continuous variable
- Box Plots: a graphical representation of the distribution of a continuous variable, showing the median, quartiles, and outliers
- Scatter Plots: a graphical representation of the relationship between two continuous variables
