Best Measure Of Central Tendency For Ordinal Data. However if you have a skewed distribution the median is often the best measure of central tendency. Once you identify a variables level of measurement you are able to determine the measures of central tendency that can be computed a given variable.
Middle number o 50 above 50below o Not affected by extreme values o Position in ordered data n1 2 Mode. The mean is usually the best measure of central tendency to use when your data distribution is continuous and symmetrical such as when your data is normally distributed. Mode Median INTERVAL VARIABLES.
However there are some situations where either median or mode are preferred.
The mode is the least used of the measures of central tendency and can only be used when dealing with nominal data. Once you identify a variables level of measurement you are able to determine the measures of central tendency that can be computed a given variable. To calculate the mean of a dataset you simply add up all of the individual values and divide by the total number of values. The most frequent value.
