You collect some random numbers and count how many of them start with 1. You then count how many of them start with 2, 3, 4 and so on until 9. Then you plot a bar graph that shows the frequency of each starting digit. You repeat this with the sum of two random numbers, the product of two random numbers, the population of each country in the world and the coastline of each country in the world; creating a bar chart of the frequencies of each starting digit for each of these collections. The question is.....how would these graphs compare? (a) All the same shape more or less (b) All the same shape exactly (c) Some exactly the same (d) All completely different. |
