Document Summary
Central tendency 2 data into a central tendency. Qualitative data/nominal variable data categories are independent. Although the categories are independent we still often want to condense: the intermediate values are meaningless. We cannot: this can lead to people thinking we can assign values to the values are equal. chronological order. Mode measures the most frequent variable in a data set: for continuous variables there may be no repeated values. A mode for continuous data may be totally uninformative: each thing may only occur once, they are never 100% accurate. Modes are more informative for grouped data sets than individual data sets. There is no (cid:498)perfect(cid:499) solution to what bin size to use: it all depends on the most useful way to describe your particular data set. What do we do if we have inconsistent modes for continuous data: we may need more than one mode for our data set.
