Oscilloscope Accuracy: Investigating Data Reliability

[gimini75]

Hi

I have done my experiment by using an Oscilloscope, (10 k ohm) resistor and 220 nF capacitor and a probe to find the the V out and then finding Gain and phase shift, my question is what's going to affect the accuracy of the data being received from the experiment results?

Have you checked the specs of the oscilloscope? There's probably inaccuracys there.
Does the scope have a scale which you read? The eye is usually good to half a division.
