which of these is an independent variable and causes variance? how to explain variations of quality scores over time how to explain variance in jitter what is difference between jitter and quality score how should jitter cause a variation in a quality score what causes loss variance variance for loss rate and loss rate which variable is a dependent variable on the quality of a cloud service? is variance caused by delay or jitter why is variance an independent variable why does loss cause variance can jitter cause variance why does quality score variance increase when loss rate is the same as quality score why would jitter be a variable in a scatter plot when the quality of data is affected by the loss rate, does the variance in the quality of the data be the same? why do jitters cause variance what is variance in quality why can loss rates cause variability why does variance occur for loss of data why does jitter cause variance
