  • The suitable IV ranges have...
    1. 5 values
    2. Cover suitable range
    3. Evenly spaced
  • Where to look for information?
    1. Background information
    2. Table
  • Worst fit - best fit
  • Best fit + or - difference
  • Comparison State for Y-intercept and X value: If the THEORETICAL VALUE fits into the range given by the graph.
  • For the graph you will NEED:
    1. Vertical error bars
    2. Regression Line
    3. Symbols matching the title
    4. Optional regression line WITH equation!
  • Uncertainty range is the range of possible values for a variable of measurement
  • Questions to ask yourself when analysing repeat trials in an investigation
    1. Have they achieved concordant results?
    2. For this, investigation how much time would it take to complete 1 trial?
  • Repeat trials are done to improve precision
  • Short amount of time (less than a day) do as many trials as you need to get (3) similar results.
  • Longer amount of time (more than 1 day) at least 5 trials to allow for some results to be discarded if they are not consistent.
  • How do we compare data?
    % difference = measure value-expected value/expected value *100%
  • Expected value = Theotrical value
  • An outlier is a data point that is different from the pattern of data
  • Outlier: Significant difference from the major trend line
  • Outliers compare to graph, table or conculsion
