It's helpful to explore our data using descriptive statistics or visualizations before using the CV. This will help us understand the distribution and identify any skewness or outliers that could affect the CV's reliability. If you want to use Excel to visualize data, check out this course on...
Find the median with ordinal data The median is usually used for quantitative data, which means the values in the dataset are numerical. But you can sometimes also identify the median forordinal data. Ordinal data is organized into categories with a rank order – for example language ability le...
Indeed, volatility itself can be volatile. It can change rapidly in response to market events, making it difficult to predict. Moreover many models that use volatility assume that price changes follow a normal distribution. However, in reality, financial returns often exhibitskewnessandkurtosis, mean...
ForSimplification Algorithm, select one of the options from the drop-down list. In this example,Retain weighted areas (Zhou-Jones)is selected. This method uses the weighted triangles of effective area, measured by comparing the flatness, skewness, and convexity of each area to guide the ...
