Learning quantitative methods sets you up to study an extensive range of subjects that fall under social sciences. You could pursue a bachelor’s in the main branches of social sciences that are psychology, sociology, and even criminology. There are many universities that offer an undergraduate degree with such titles as “Bachelor of Science in criminology with quantitative methods”. You may go on to complete your master’s in the field you choose and even go up to a PhD.
If you wish to choose a different path than what has been normally laid down, you can also get a bachelor’s in geography with QM since geographers have to use statistical data during fieldwork.
You might be surprised to hear that you can also get a bachelor’s in political sciences with quantitative data, as politicians and government agencies use data to measure voter behaviour. Similarly, some universities have also started offering a bachelor’s in social policy.
