1.
Which spreadsheet formula gives the mean of cells B2 to D2?
=AVERAGE(B2:D2)
=SUM(B2:D2)
=MEAN(B2+D2)
=B2/D2
2.
A good chart type for plotting speed against time is:
pie chart
scatter plot
bar chart
line chart with category axis
3.
A trendline equation is y = 4.02x + 0.01 for T2 against L. The value of g from 4π2/gradient is about:
4.0 m s−2
39 m s−2
9.8 m s−2
0.10 m s−2
4.
R2 = 0.99 for a straight-line fit means:
the model is certainly correct
there are no uncertainties
the intercept is zero
the line follows the data closely, but the physics must still be checked
5.
Forcing a trendline through the origin is justified only when:
the physics requires zero at zero
it gives a nicer graph
the intercept is large
the data are noisy
6.
A fit of ln A against t has gradient −0.12 s−1. The half-life is:
0.12 s
5.8 s
8.3 s
0.69 s
