Explanation / Answer

Answer:

For the given scenario, data is categorical in nature. The categorical variable offense has six categories. The level of measurement is nominal for the given scenario.

For the given data for the number of suspects for different types of offence for the year 2009 and 2012, it is observed that there are outliers present in the data for the category immigration.

If there is an outlier present in the data, these outliers affect the arithmetic mean or average of the data. Arithmetic mean is not suitable in this case. Instead of using arithmetic mean, we will use median as the measure of central tendency for the given scenario.

We know that the outliers present in the data also affect some measures of variability such as variance, standard deviation, range, etc, but the inter-quartile range is not affected by the outliers or extreme observations of the data. So, we will use the IQR or interquartile range for the measure of variability.
