Study Questions

Chapter 3

The following data are taken from Statistics Netherlands, which collects and processes data for use by policymakers and for scientific research (

The rate of divorce in the Netherlands has generally been increasing over time. Below are presented divorce rates per 1,000 persons over 7 time periods.

1950 0.64
1960 0.49
1970 0.79
1980 1.82
1990 1.90
2000 2.18
2007 1.95
  1. Construct a time series chart displaying this information. Be sure that you correctly specify which variable belongs on the horizontal and vertical axes.
  2. Using the time series chart that you constructed in Question #1, describe trends in divorce in the Netherlands before and after the 1970s.
  3. As is evident from the time series chart you constructed in Question #1, there was a drop in the divorce rate between 2000 and 2007. Does this mean that there were a negative number of divorces taking place? Explain.
  4. Returning to the original data provided at the outset of this question set, which would be the appropriate graphic devise for these data, a bar graph or a histogram? Why?
  5. Based on your answer to Question #4, construct the graphic device that you identified as most appropriate.
  6. In 2007, the population of the Netherlands was 16,357,992 persons. Total population growth year was 47,407 persons and composed of the following elements:
Births 181,336
Deaths 133,022
Immigration (those who entered the country 166,819
Emigration (those who exited the country) 122,576
Administrative corrections 4,850

Excluding administrative corrections, construct a pie chart which shows how each of the remaining four elements contributed to population change in 2007.

  1. Again, excluding administrative corrections, construct a pie chart showing the relative contribution elements which contributed to population growth. (Hint: population growth is a product of births and immigration. So, you will only want to consider these two elements).
  2. Provided below are data on the male and female population in the Netherlands over the past 8 years. Construct either a frequency polygon or a time series chart using the data provided which shows changes in the male and female population over the last 8 years.
  Male Female
2001 7,909,855 8,077,220
2002 7,971,967 8,133,318
2003 8,015,471 8,177,101
2004 8,045,914 8,212,118
2005 8,065,979 8,239,547
2006 8,077,407 8,256,803
2007 8,088,514 8,269,478
2008 8,112,073 8,293,326
