Semantic differential

Semantic differential is a special tool that is used to measure how people feel or think about something. Imagine you have a big piece of paper in front of you that has a line drawn down the middle. On one end of the line, there is a happy face, and on the other end of the line is a sad face.

Now, let's say we want to know how you feel about ice cream. We would ask you to mark an "X" on the line to show how much you like it - closer to the happy face if you love it or closer to the sad face if you don't like it at all.

But we can also use other pairs of words instead of happy and sad faces, like "boring" and "exciting" or "calm" and "chaotic." By doing this, we can get a better understanding of how people feel or think about different things, and we can compare their responses to find out which things are more exciting or calm or satisfying, for example.

Overall, semantic differential is a way to help us understand what people think and feel in a more structured and organized way so we can see patterns and trends.
