Task 3:
Multiple regression analysis was used to test the accuracy between my estimated distances
between pairs of cities in New Zealand, and its true distances. My estimates were captured by
a straight line, maintaining a close estimation to the true distances. A small degree of freedom
indicates a strong correlation between our two variables, suggesting that my mentally mapped
estimated distances were close in accuracy. The Multiple R value of 0.98 indicates a very
strong linear relationship between the two variables. A significant p value indicates statistical
significance of the regression model.
The slope of the best fitting line is y =1.2098x - 63.82. The negative coefficient value -63.82
reveals that as the estimated distance increases, the true distance decreases. There is a
significant decrease between the values of the true distances with the estimated distances, t(1)
= -2.11. This suggests that I tended to overestimate the value of linear distances between city
pairs when mental mapping; this is also evident in Figure 3. The results of the regression
indicate that 95.41% of the variance in the true distances can be explained by the estimated
distances (R2 =0.9541, F(1, 539.98) = 6.43, p = 0.05).
