# Thread: mode of frequency curve

1. ## mode of frequency curve

given x=8.9,9.0,9.3 the corresponding y=0.30,0.35,0.25
calculate mode of frequency curve using langrange interpolation
i know how to make a function with langrange interpolation but how to find mode of frequency curve

2. ## Re: mode of frequency curve

once you've got your interpolation function find it's maximum. The x value corresponding to that maximum is the curve's mode.
