− | A trend is an association between time and a measurement. A trend hypothesis argues that this measurement depends on time. AmCAT provides you with various possibilities to analyse trends. Using AmCAT, you can visualize a trend graphically any draw preliminary conclusions about the trend. You could, for example, test whether a trend is linear or cyclic. To display a possible trend in a graph you can use the graph function in the [[3.4:Graph | + | A trend is an association between time and a measurement.

To display a possible trend in a graph you can use the graph function in the [[3.4:Graph/Table|Graph/Table function]]. AmCAT also provides you with the possibility to produce data with which you can perform a formal test of the trend hypothesis. To test whether a certain trend exists (i.e. whether a measurement depends on time), you export the AmCAT output by clicking 'Export Aggregation' and analyse the data in a statistical program. |

− | Lastly, you can extrapolate your findings based on the differences observed between certain units. You could, for example, compare articles from different media/sources, debates within the field of politics versus media, attention for a concept in period A verus B, et cetera.
