You may find that Greek letters and mathematical symbols become the victims of a font replacement when you download! e.g.  A 'D'  might need to be changed to the greek letter delta !

Excel for the 3-1 Investigation PART ONE

Tasks and Intended Outcomes

  1  To plot a basic line graph (x-y scattergram) from two columns of data.

  2  Modify a basic graph to include the detail and axis labelling required for NCEA.

  3  Modify an existing graph to include vertical, fixed value error bars.

  4  Use a formula to average a range of data and format the answer to 2d.p.

  5  Use the MAX and MIN functions to find the half-range of a set of data and complete a data table.

  6  Enter a formula to convert absolute uncertainty to percentage uncertainty.

  7  Use the SQRT function to reprocess values L > L  and calculate the uncertainty of the processed data.

Excel for the 3-1 Investigation PART TWO

Tasks and Intended Outcomes

  1  Modify a basic graph to include the detail and axis labelling required for NCEA and identify the relationship

  2  Reprocess the independent variable data appropriately for the relationship

  3  Complete a data table to find the absolute uncertainty of the reprocessed (squared) variable

  4  Plot an x-y scattergram to get the straight line graph from the relationship.

  5  Modify a graph of the data to show a trendline, equation and produce customise error bars from the data table

Excel for the 3-1 Investigation PART THREE

Tasks and Intended Outcomes

   0  Information about the experiment and relationship - no modification required.

  1  Modify a basic graph to include custom error bars, insert the generic equation then    modify the equation to include the appropriate variables and insert a suitable error line onto the graph.

  2  Calculate and compare gradients of the two lines to find the uncertainty of the gradient

    State the mathematical relationship including appropriately rounded uncertainties.

  3  Compare results with an exemplar
