IMS Needs Assessment Survey--Section 8

8. POPULATION BY TYPE OF MUSEUM

CLASSIFYING RESPONDENTS BY TYPE OF MUSEUM

We classified each eligible respondent as to whether it was a small, emerging, minority or rural museum, as defined in Section.

1 Small Museums

We classified an eligible respondent as a small museum if it gave the required response to either of two questions:

Question 2. Must respond that it has five or fewer full-time staff.
Question 14. Must respond that its operating budget is less than $250,000.

If the respondent gave contrary responses to both these questions, then we classified it as not a small museum. If it gave the required response to neither question, but failed to answer at least one of the questions, then we classified its small museum status as unknown.

8.1.2 Emerging Museums

We classified an eligible respondent as an emerging museum if it responded to Question 6 that it had done at least one of the things listed in the definition of an emerging museum. Question 6 also asks whether the respondent has significantly reduced its operations, which is unrelated to the definition of an emerging museum. We ignored the response to this part in classifying respondents as emerging museums.

Question 6 asks whether the respondent has developed a long range plan, while the definition of an emerging museum refers to developing its first long range plan. We ignored responses to the long range plan question in classifying respondents as emerging museums. This tends to undercount the number of respondents that are emerging museums.

If a respondent did not answer that it had performed any of the required actions, then we classified its emerging status as unknown. The questionnaire did not provide a basis to determine that any respondent was not an emerging museum.

8.1.3 Minority Museums

We classified an eligible respondent as a minority museum as follows.

If the respondent's answer to Question 21 was "yes", then we classified it according to its answers to Questions 22 and 23:

If its answer to at least one of Questions 22 and 23 was "yes", then we classified it as a minority museum.
If its answered "no" to both Questions 22 and 23, then we classified it as not a minority museum.
If it did not answer Question 22 and did not answer Question 23, or if it answered "no" to one of the questions and did not answer the other, then we classified its minority status as unknown.

If its answer to Question 21 was "no" then we classified it as not a minority museum.
If it did not answer Question 21, then we classified its minority status as unknown.

4 Rural Museums

We classified an eligible respondent as a rural museum if it selected "rural area" in its answer to Question 13. If the respondent did not select "rural area", but selected "suburban area", "urban area" or "inner city", then we classified it as not a rural museum. If it did not select any of these terms, then we classified its rural museum status as unknown.

5 Eligible respondents by type

Table shows the results of our classification.

            TABLE : ELIGIBLE RESPONDENTS BY GROUP AND STRATA

                     Eligible Ineligible Unknown

Stratum:                Apparent Minority
Small                      16      3     1
Emerging                   12      0     8
Minority                   14      6     0
Rural                       9     11     0

Stratum:                       Others
Small                     222     77    14
Emerging                  163      0   150

Rural                     131    166    16

ESTIMATING POPULATION

We estimated populations of small, minority and rural museums in each stratum as follows:

Population@st=Eligibles@sty/(Eligibles@sty+Eligibles@stn)*
    Eligibles@s*Weight@s

where:

  Population*st is the estimated population of museums of type t in
  stratum s

  Eligibles@sty is the number of eligible respondents in stratum s that
  we classified as "yes" for being of type t

  Eligibles@stn is the number of eligible respondents in stratum s that
  we classified as "no" for being of type t

  Eligibles@s is the total number of eligible respondents in stratum s

  Weight@s is the response weight for stratum s, as described in
  Section.

We did not use the above equation to estimate the population of emerging museums, because the design of the questionnaire did not allow us to distinguish respondents who did not fit the definition of emerging museum from respondents who merely failed to answer the question. Therefore, we obtained a low-end estimate of the population of emerging museums as follows:

    Population@st = Eligibles@sty * Weight@s

The following table shows our population estimates. The total number of rural museums that we report in Table is based on the share of all museums that described their location as rural, as estimated in Section, and differs slightly from the estimate here due to sampling variance.
