Bivariate data involving time, or time-series data is two-variable data where the independent variable is time. We can use line graphs to see the trend of the data over time.
Time series graphs are pretty easy to interpret, have a go at this activity below.
A time-series graph is very easy to make, simply plot the points and connect up using straight line.
We can use technology such as google sheets or excel to produce time series graph with ease.
Progressive overload is one element of fitness principals that incorporates time series graphs. Below are two graphs which demonstrate progressive overload in a graphical form.
Complete the activities below to link time series graphs to components of fitness and consider how they can inform your training plan.
Looking at the graphs above what explicitly do you see, what key things do you notice?
What do you think the graphs are showing you? What do you think is going on?
What does it make you wonder? Do you have any questions from this?
