Step 1
Categorical data - The variables in data contain groups that are called categorical data. The participants can belong to any one of the group.
Numerical data- The data contains only numerical values are called numerical data. They can be as continuous or interval data.
Step 2
a) Position of university staff members - categorical data, (as the staff members can belong to any of the various positions in the university).
Bar charts, Pie charts can be used to display the data.
b) Weight of participants. - numerical data, (as the weight of the person Is measured in numerical values).
Histograms can be used to display the data.
c) Air temperature on the Celsius scale - numerical data, (as the temperature is measured in the numerical values in the celsius scale).
Histograms, line graphs, weather graph can be used to display the data.
d) The daily number of code lines written by a programmer - numerical data (as the number of code is taken as count in numerical).
Histograms can be used to display the data.
