2) Why is Standard Error of the Mean (SEM) referred to as an error? 3) What is the relationship between the alpha value and the research hypothesis in statistics? 4) Using diagrams demonstrate two options for "Conceptualization of Neighbourhood" in spatial statistics such as Moran's I or GWR. 5) What is the meaning of Spatial Autocorrelation? Give two reasons why it is important in spatial statistics. 6) With the help of a diagram explain why the ANN index is sensitive to the size of the study area. 7) Using a diagram explain the normal probability distribution curve. How does it relate to standard deviation? What are the key parameters in the equation defining the normal probability distribution curve? 8) Imagine you have observed that in informal settlements there appears to be more open containers (which could be breeding grounds for mosquitos) than in the rest of Suva City. You wish to use a one-sample t-test to test investigate this. State the null and alternative hypothesis. You run the test and the p-value is 0.065. If you decided to use alpha (a) of 0.05, what do you conclude from your test? How confident are you in your conclusion? 9) What is multicollinearity? How can you detect multicollinearity and explain what you might do to correct the problem if you find that multicollinearity is too high. 10) Briefly explain the major difference between deterministic and stochastic interpolation methods. Be sure to identify at least one benefit of each. You may use diagrams but it is not necessary.
