2.4. DEALING WITH PUBLISHED
You may be interested in statistical information collected either nationally or locally. Some
researchers have used published statistics as their only or their main source of evidence. For example, it is
possible to compare aspects of educational provision in different LEAs in England and Wales by drawing
on statistics
published by the authorities or by the DES. (Section 6 of this Handbook lists several sources of
national statistics.)
INTERPRETING STATISTICAL INFORMAT ION
Published statistics are often presented in the form of tables. These are not always easy to use.
They may not contain quite the information you want, or they may contain too much information for your
purposes. Examples 2.3 and 2.4 below show two tables that provide information on the number of pupils
that stay on at school after the age of 16, but they provide slightly different information and they present
the information in different ways. Both examples give separate figures for pupils of different ages (16-,
17- and 18-year-olds or 16-, 17-, 18- and 19-year-olds). Both allow comparisons to be made between girls
and boys, and between staying-on rates in different years (but not the same set of years).
Example 2.3 covers the whole of Great Britain (England, Scotland and Wales but not Northern
Ireland). The table presents staying-on rates in the context of 16- to 18-year-olds' 'educational and
economic activities'. It allows comparisons to be made between the percentage of young people who stay
on at school and the percentages who are engaged in other activities. But different types of school are
grouped together. (It is not clear whether the table includes special schools.)
Example 2.4 covers England and Wales. It gives figures for 16-, 17-, 18- and 19-year-olds as a
percentage of the relevant cohort of 15-year-olds one, two, three or four years earlier. It does not give any
information about what young people who aren't at school are doing. But it does distinguish between
maintained and non-maintained schools. It also explicitly excludes information from special schools.
If you wanted to know, say, the percentage of 16-year-olds who stay on at school nationally, the
tables give similar figures: 31 per cent in 1988 in Example 2.3 and 30.1 per cent in 1988 in Example 2.4.
(The slight discrepancy may be because of differences in the samples drawn on in each table.) But
Example 2.3 masks large overall differences between maintained and non-maintained schools, and a
small gender difference in maintained schools that is reversed in non-maintained schools. Both tables
mask regional variation in staying-on rates (another DES table gives this information) and variation
between pupils from different social groups - except in so far as maintained and non-maintained schools
are an indicator of this.
When drawing on published statistics, therefore, you need to check carefully what information is
given. Does this have any limitations in relation to your own research questions? Is there another table
that presents more appropriate information (e.g., information from a more appropriate sample of people or
institutions)? It is important to look at any commentary offered by those who have compiled the statistics.
This will enable you to see the basis on which information has been collected – what has been included
and what has not. If you are using local (e.g. school or local authority) statistics it may be possible to
obtain further information on these from the relevant school/local authority department.
DRAWING ON PUBLISHED ST ATISTICS IN YO UR REPORT
You may wish to reproduce published statistics in your report, but if these are complex tables it is
probably better to simplify them in some way, to highlight the information that is relevant to your own
research. Alternatively, you may wish to quote just one or two relevant figures.
Example 2.5 shows how the table in Example 2.3 has been adapted and simplified by June
Statham and Donald Mackinnon (1991), authors of a book on educational facts and figures designed for
Open University students. Statham and Mackinnon present information from the original table as a
histogram. They give combined figures for girls and boys to show overall staying-on rates. But they
import information from another table to enable them to make a comparison between 1988 and 1980.
They comment: 'During the 1980s, there has been a slight increase in the percentages of young people
