Population: Distribution, Center, and Spread
Lab
Work in teams to answer the following questions based on your sample of Census Registration Districts.
1. Calculate the mean, the median, and the range for the population in 1851 and in 1861 within your sample districts.

What do these measures indicate about the distribution and change of the population in your sample districts?
2. For each of your districts, calculate the change in the population from 1851 to 1861. Then calculate the mean, median, and range of these changes

What do your results indicate about population change within your sample?
2. For each of your districts, calculate the percentage change (increase or decrease) of the population in 1861 compared to that in 1851.
What patterns seem to emerge from your results?
3. Now that you have determined the change in population from 1851 to 1861, determine what portion of this is attributable to migration into or out of your districts. (Hint: first add TotalF and TotalM (population changes due to female and male migration; then divide the result by the population in 1851.)
What can you conclude from your results about the significance of migration among your sample Registration Districts?
Study the figures on migration for different sex/age groups (Females 15-25 and 45 to 54; Males 15-24 and 45 to 54). Devise a method of exploration and search for meaningful patterns in these figures. What does your exploration show?
