How to Analyse Time Series Results
Conjointly’s Time series report simplifies the process of analysing results by time periods (called waves), making it easier to identify trends and shifts in respondent attitudes and behaviours over time.
Setting up time series in your report
Time series can be set up by navigating to the Time series tab next to the Insight tab within your report. Please note that the tab will not be available if your report consists only of conjoint or monadic blocks.
By default, the report’s results are split into two equal waves.
