Supporting this view, other theories combine the concepts of active audience theory and the effects model, such as the two-step flow theory where Katz and Lazarsfeld argue that persuasive media texts are filtered through opinion leaders who are in a position to 'influence' the targeted audience through social networks and peer groups.

In 1993, the communication scholars Denis McQuail and Sven Windahl referred to Lasswell's model as "perhaps the most famous single phrase in communication research." [18] McQuail and Windahl also considered the model as a formula that would be transformed into a model once boxes were drawn around each element and arrows connected the elements. [18]
The model was originally rooted in 1930s behaviourism and was largely considered obsolete for a long time, but big data analytics-based mass customisation has led to a modern revival of the basic idea. After that, a shift which rediscovered the relationship between media and people occurred and led to establishment of uses and gratifications ...
This value is then subtracted from all the sample values. When the samples are classed into equal size ranges a central class is chosen and the count of ranges from that is used in the calculations. For example, for people's heights a value of 1.75m might be used as the assumed mean. For a data set with assumed mean x 0 suppose:
The propaganda model relates to news media, which includes 5 filters which suggests how the news is "filtered" and edited into a content that suits the demand and interests of those people who have more power and wealth, especially corporations and the government.

If the dataset is, e.g., the values {2,3,5,6,9}, then if we add another datapoint with value -1000 or +1000 to the data, the resulting mean will be very different from the mean of the original data. Similarly, if we replace one of the values with a datapoint of value -1000 or +1000 then the resulting mean will be very different from the mean of ...
