Surveys and Data Entry System

Test & Pilot your survey !

Evaluate the competency of the questionnaire. Estimate the length of the survey or time to take

the survey. Determine the quality of the surveyor.

Before you start

Do the respondents understand the survey’s objective? Do the respondents feel comfortable answering the questions? Is the wording of the survey clear? Is the time reference clear to the respondents? Are the answer choices compatible with the respondents’ experience in the matter? Do any of the items require the respondent to think too long or hard before responding? Which ones? Which items produce irritation, embarrassment, or confusion? Do any of the questions generate response bias? Which ones? Do the answers collected reflect what you want in regards to the purpose of the survey? Is there enough diversity in the answers received? Is the survey too long? According to your test audience, have any other important issues been overlooked?

Surveys and Data Entry System

Database must be developed when you need to UPDATE

If it's a one time data entry, use a dedicated survey application – no need to code

Get the printed form from the application rather than redoing in Word/Excel

Descriptive analysis & Exploratory analysisAnalysis

1. Descriptive statistic are mostly “Univariate analysis”. It involves the examination across cases of a single variable, focusing on three characteristics: the distribution; the

central tendency; and the dispersion

Example: a frequency distribution chart

2. Exploratory analysis is an approach to analyzing data for the purpose of formulating hypotheses. “Multivariate or Factor analysis” are used to uncover the latent structure (dimensions) of a set of variables. It reduces attribute space from a larger number of variables to a smaller number of factors and allows the definition of

statistically consistent cluster.

Example: Multivariate cluster analysis from three measurements of femur properties

From Wikipedia

Possibility to define the characteristics of statistically homogenous groups. Those characteristics can then be used to build targeted assistance programme!
