2. Statistical Reliability

The sample tolerances which apply to the percentage results in this report are given in the table below. This table shows the possible variation that might be anticipated because a sample, rather than the entire population, was interviewed. As indicated, sampling tolerances may vary with the size of the sample and the size of the percentage results.

For example, on a question where 50% of the people in a weighted sample of 989 respond with a particular answer, the chances are 95 in a 100 that this result would not vary more than 3 percentage points, plus or minus, from a complete coverage of the entire population using the same procedures.


Approximate Sampling Tolerances Applicable to Percentages at or near these levels
10% or 90%30% or 70%50% or 50%
±±±
989 (all)233
527 (ambulant disability)344
314 (wheelchair user)356
210 (visually impaired)467
163 (hearing impaired)578
157 (learning disability)578
406 (urban excluding London)355
311 (rural)356
272 (London)466

Tolerances are also involved in the comparison of results from different parts of the sample - e.g. between the results from different sub-groups or from different samples over time. A difference, in other words, must be of at least a certain size to be considered statistically significant. The following table is a guide to the sampling tolerances applicable to comparisons. The differences between the survey findings must equal or exceed the percentages shown here for the difference to be considered statistically significant. The difference required varies depending upon the sample sizes in question (first column) and the survey finding (columns 2-4).

4. About MORI

Set up in 1969 by Professor Robert M Worcester, MORI (Market & Opinion Research International) is the largest independent full-service research agency in Great Britain. MORI has research expertise in many specialist areas - including transport research. MORI undertook the 2000 and 2001 CfIT research, and has also conducted a number of other major studies on public attitudes to the transport system and transport policies. MORI also runs the People's Panel research programme on behalf of the Service First Unit at the Cabinet Office - data from which has been incorporated into this report.

Ranked 8th overall in the 2001 British Market Research Association (BMRA) League Table, MORI's turnover in 2001 was £34 million. MORI has been the fastest growing top ten market research agency for the past two years.

MORI is also the British representative of the IriS (International Research InstituteS) network of European and international research agencies. Through the MORI group of companies and the IriS network, MORI can offer clients access to an international research service network, which ensures the highest technological expertise together with a real capacity for handling operations at a regional level, in virtually any part of the world.
