As Level Physics - Practical on Stationary Waves, Analysis, HELPPP

I.Want.To.Pass

I'm doing a practical, and I got results through experiment of measuring a Stationary Wave on a String using a Vibrator Generator, connected to a string, and a tension is added. We calcuated the approximate frequency through eye measurement of the highest amplitude/displacement.

I'm having trouble doing the Analysis part.
So this is the Layout of the Analysis, and what to include:
- Trend,
- Prediction,
- Theory,
- Uncertainties -> Significance?
Graph - If they pass through the orgin?
Sources of errors - That dont make it pass through the origin?
Suggestion Improvements?
Conclusion...

Please help me, I'm really struggling. I have lengths (m) from 1.35-0.45, (within 6 repeats of different lengths), and my average Frequency of 3 trials of each length increases as length decreases. But my 1/Hz ^-1 (Inverse Frequency) Decreases as Length decreases.

My Hypothesis is - As length decreases, the Frequency will consequently Increase, with constant Tension, etc.

So How would you apply these results, and how do i put it in my written Analysis.. I don't know what to include.... :/ HELP
