Study Notes
Measures of Central Tendency
- The mean is the average of a set of numbers. The formula for sample mean is ∑x/n where x is the observation and n is the number of observations.
- The median is the middle value when a dataset is arranged in order. Half of the values are above the median, and half are below.
- The mode is the most frequent value in a dataset. It can have multiple modes or no mode at all.
Methods for Dealing with Outliers
- A trimmed mean discards data from the highest and lowest values to help in reducing the effect of outliers.
- A winsorized mean substitutes values for outliers instead of discarding them.
Measures of Location
- A quantile is a value below which a specific proportion of the data in a distribution lies.
- Examples include, quartiles (25% intervals), quintiles (20% intervals), deciles (10% intervals), and percentiles (1% intervals).
- The interquartile range is the difference between the third and first quartiles which can help to identify outliers.
- A box and whisker plot helps to visualize the distribution of data. It shows the range of data values, the quartiles, and potential outliers.
Measures of Dispersion
- Dispersion is the variability around the central tendency.
- In finance investments, there's a trade-off between reward (central tendency) and risk (dispersion).
