Common mistakes Expecting access to data that exist

There are many reasons why the data owner may not want

to divulge further details or may not be able to help you.

One reason is that storage space costs money. They may be located in buildings that are secure and not easily accessible. They may only be available on microfiche, in which case, specific apparatus must be available for viewing and data transfer. Even software and hardware have both changed over the years. On the Internet, we may find that web addresses have been changed, password protected, or entire archives have been removed. A solution to some of these problems is to use the Internet Archive’s ‘way back machine’. The Internet Archive is building a digital library of Internet sites and other cultural artefacts held in digital form. Like a paper library, the archive provides free access to researchers, historians, scholars, and the general public (http://www. archive.org/). Very often web addresses that are not accessible, or have been removed, can be found by typing the address into the archive search form. The UK Web Archive has been collecting UK websites since 2004 in the same way (see http://www.webarchive.org.uk).

Things that must be considered in ‘reverse researching’

Item

Missing data Nothing is complete, but detecting what is missing can be informative

Mistakes Simple spelling mistakes may be indicative of a lack of attention to

detail; continue checking to identify any numerical errors

Poor expression

Poor expression is a problem, especially with texts that have been produced in a language in which the original researcher is not fully

fl uent. The sense may have become corrupted

Deliberate bias

The initial reason for any document is to achieve some objective. This tone can sway the desk researcher

Scales May bias the data in a specifi c direction

a term, enables policymakers to determine the most and the least popular decisions. Long-

term studies indeed show trends, but peaks and troughs can sometimes be attributed to

changes in the data collection method rather than real changes. For example, the 1881 and

2001 censuses cannot be compared without accounting for basic diff erences. The report-

writer must therefore be prepared to delve into studies far more deeply than might be

anticipated.

To assess the reliability of information, it is useful to look at the source and the context.

Table 3.13 shows a way to assess a particular piece of information. A score is given for these

two characteristics. If the total is six or above, then the information is likely to be trustworthy; if

it is fi ve or below, then use of the data should be made with caution.

Analysis for the purposes of the current research problem inevitably means that the

information may need to be reworked or combined in some way (see Figure 3.7). This

reworking or combining information from diff erent sources is a form of ‘data fusion’: a technique that has become more sophisticated and largely automated in recent years.

For any sector, the following information should be compiled to give a complete picture:

• Six top companies

• Six important trade press titles

• Three trade associations

• Two trade directories.

A web resource created for the UK market research industry http://www.mrweb.com/ sectors/ illustrates this well by giving instant links to sectors such as fi nance, pharmaceuticals, and many more (see Figure 3.7).

There is a distinction between synthesis and analysis that is worth stressing. ‘Synthesis’

is essentially description; there is little critical input apart from the decision about what to include and what to exclude. ‘Analysis’ implies creating an analytical framework that gives some structure that can be transferred to other evidence, to other cases. It implies the creation of a problem-solving tool. Many such tools have been adopted in the past: any matrix, a SWOT report, a PEST analysis, even the four Ps of the marketing mix.

Recording and reporting sources

In the business environment, reports are not expected to carry references to every statement made. This is primarily to remove irrelevant reading matter from reports, on the assumption  that what is written is more important than who wrote it originally. This can

be quite alien to the academic who is well versed in the Harvard system of referencing, whereby any new fragment of knowledge is attributed to the originator. In many ways, business reporting is more diffi cult for the researcher because any point may be challenged

by users of the information; they will evaluate the usefulness of decision-making material in many ways, so you may well need to show the exact origin and method used to acquire the data. A second purpose for keeping detailed records is to make newer searches in a focused way and to avoid repeating abortive searches. For these reasons, it is crucial to keep good clear records.

There are two important exceptions to the attribution of sources: tables will carry a source with date and the report appendix should carry a summary of the main sources (and methods used). The ‘private’ records kept by the researcher should allow further detail to be provided when requested, or to extend a project beyond the initial phase. These records will be in the form of notes, photocopies, fi ling index cards; online searches will result in downloaded fi les that should also be kept in some form of system. The sources and dates of access should be recorded in all cases.

Explain the nature of secondary data

Secondary data are best remembered as ‘second-hand’, because such data are ‘old’ primary data.

This involves more than consulting documents; it also involves expert interviews with people.

Internal secondary data are generated by the organisation in question, whereas external secondary

data are created by agencies outside the firm. The term ‘tertiary data’ refers to indexes, citations to

articles, and summaries or abstracts; in simple terms, these are ‘third-hand’ data.

Outline the different sources of secondary data

Internal secondary data include: sales force records, transactions, competitor activity, customer

records, inventory records, cost of transport, previous research, and website visitor records.

External secondary data include government output, academic knowledge, and company reports.

Professional associations publish industry overviews. Market research report publishers have

reports on different market sectors. Geodemographic companies produce data from the census combined with other databases. There are also ‘consumer-generated media’ (CGM).

Show the benefits and the limitations of using secondary data Secondary data have various uses—they may answer the research question; they may also help to refine objectives, to design primary research, to assist in sampling, and to supply pre-codes for questionnaires. Secondary sources can be used in conjunction with primary research, for example,

to enhance understanding of and to confirm results. Secondary data are likely to be less expensive than collecting information freshly. They are relatively easy and quick to obtain: a unique benefit for international studies. However, secondary data have already been collected for something other than the current research problem. Therefore, they may not address the topic in question or may only provide part of the information expected. The information may not be accurate or it may

be outdated. Additionally, data may not actually exist, or may have restricted circulation.

List the features of a plan to carry out effective searches Three approaches are likely: visits to general and specialist libraries, contacting human experts, and carrying out computer searches. For all of these, the desk researcher must set limits on time spent, cost expended, number of sources searched, language used, age of sources, format of data, and methodology used. Continuous needs for data will make it feasible for the researcher to implement permanent information requests; conversely, the occasional requirement points towards gleaning information quickly. Desk research will start with the Internet, so the user must be familiar with search tools and techniques. To assess the reliability of information found,

it is useful to look at the source and its context. Use the MR mix to ascertain the original purpose, the population used, the procedure followed, and the reason for original publication. For any

sector, look for the top companies, important trade press titles, trade associations, and trade directories.

guide. Discover the services available and the user guides. Be sure to see Google Scholar

and Google Analytics. Write a report on your findings.

3 We want to find some information about the music business in Italy. First, generate some

synonyms using a thesaurus (either a real book or one built into your software). Next,

translate these words from English to Italian using a language translator. Then cut and

paste these words into a search engine and look at the results. Read each of the websites

by selecting the word ‘translate’ at each result.

4 Consult the proposal in the Market Researcher’s Toolbox. Draft a possible design for

secondary data collection. Try to list precisely what you will do. A second task is to carry

this out.
