I want to figure out variance over time

I have some data set i collected. I was asked to plot variance and can i plot variance over time. I have 100 data for 20 seconds.Is it possible to plot variance over time or only one variance ?

Solution

  • It is possible to plot variance over time. For example, you can find the variance of data points 0 to 10, then 1 to 11, then 2 to 12... and then plot that against 0, 1, 2...
