It is the distribution of observed time across behaviors such as resting, feeding, moving, and social interaction. Researchers use it to compare behavioral strategies between groups, habitats, or seasons.
Percentages standardize behavior time so you can compare animals or studies with different observation lengths. They are often the clearest way to summarize budget structure.
Coefficients let you assign extra weight to behaviors that may be more costly, intense, or biologically important. They do not replace raw time values; they add an interpretive layer.
Yes. Enter the actual observation hours per day and the number of observation days. The calculator then reports coverage so you can judge how complete the dataset is.
It scales each observed proportion to a full 1440-minute day. This is useful for comparison, but it assumes observed proportions reflect the broader daily pattern.
It measures how spread out the time budget is across behaviors. Higher values indicate more balanced use of multiple activities rather than strong dominance by one category.
Low coverage means many minutes in the study window were not logged. That can weaken interpretation, especially when projecting to a full day or comparing different datasets.
No. It is a structured summary tool. Behavioral coding quality, sampling design, observer bias, and species-specific ecology still need expert interpretation.
