Studying a proportion of individuals or cases from a larger population as representative of that population as a whole.

Sampling

Explanation:

Sampling is the process by which we select a representative number of cases present in the population (called "sample") that will guide our observations and statistics, so we can infer from the population present in that universe.

This subset or sample will result after we select units from a larger population and it will enable us to make generalizations about the original population from which they were picked.

Sampling is required in any quantitive research,  and in some instances, there is a qualitative approach. They are called qualitative sampling: purposeful sampling, quota sampling, and snowballing sampling.

new communications technology has affected the way social movements are organized because nowadays, social movements rely on social networks and the media to get different people with a similar way of thinking in contact, and thus, get them to mobilize for a greater cause.

individuals only participate in collective action when they feel identified with it. is in this aspect that social media becomes relevant, because it guarantees communication among all individuals and organizes the social actions that are going to be carried out, i.e., the social movements.

in addition, being covered by the media is important to validate the message and make it relevant in the social agenda, as well as to reach more people who can share interests, appealing to public sympathy for their cause.

in conclusion, it is by social networks and social media that social movement is given birth; by connecting different individuals with similar ideas and organizing them to mobilize for a greater cause.
