B) 4 variables, 2 of which are categorical
C) 3 variables, 1 of which is categorical
D) 3 variables, 2 of which are categorical

Answer 1

The individuals in this data set are C) Cities

Same idea as last time, but now we're listing cities and their associated weather data.

=============================================

The data set contains B) 4 variables, 2 of which are categorical

The four variables are

1. high temp (degrees celsius)
2. kind of precipitation
3. average wind speed (in km/hr)
4. severe weather alert

The two categorical variables are "kind of precipitation" and "severe weather alert". This is because the choices for each of these variables is a list of labels rather than numeric values. We cannot do things like find the average of the kind of precipitation as it doesn't make sense to do so. Each of these categorical variables are also nominal. This means they simply have a label or name. We cannot do things like order the data.
