What measure of central tendency should be used when your variable is ordinal?

When dealing with ordinal variables, the most appropriate measure of central tendency to use is the median. The median effectively captures the central point of the data by identifying the middle value when the data is ordered, which is suitable for ordinal data that has a rank order but does not have consistent intervals between values. The mode can also be used, especially if the most common category is of interest, but the median typically provides a better representation of the central tendency in ordinal data.


What kind of conclusions could you make about box and whisker plots?

It is a useful scheme to summarise data. It provides information on the central tendency (median) and a measure of spread (inter-quartile range). The total range is also indicated and outliers are separately identified. The location of the median within the IQR "box" provides an indication of the skewness of the data.


Which measure of central tendency would be most?

The most appropriate measure of central tendency depends on the nature of the data. The mean is useful for normally distributed data without outliers, while the median is better for skewed distributions or when outliers are present, as it provides a more accurate representation of the central point. The mode is ideal for categorical data where we want to identify the most frequently occurring value. Therefore, the context and characteristics of the data should guide the choice of measure.


What central tendency can be used on ordinal data?

For ordinal data, the median is the most appropriate measure of central tendency, as it effectively represents the middle value in a ranked order. While the mode can also be used to indicate the most frequently occurring category, the median provides a better summary of the data's central point, especially when the data is not symmetrically distributed. The mean is generally not suitable for ordinal data due to the lack of equal intervals between ranks.

You can tell you are rotating if you are spinning around an axis. You can tell you are revolving if you are moving in a circular path around a central point. These motions can be observed by tracking changes in position relative to a fixed point or axis.
