The questions you ask of respondents are the ultimate core of every survey 
		project. The entire effort is directed towards inquiry, and the questions are 
		the elements that perform the actual interrogation. Based on your objective, 
		you have to decide what types of questions will give you the information you 
		need. Each question type is unique and provides different types of data. In 
		this article, we will be addressing the different question types available with 
		eSurveysPro and how to use them in creating surveys. We will also discuss the 
		different data validation techniques that you can use to optimize results. 
		eSurveysPro helps you develop your surveys quickly -- and save your specialized 
		questions to assure consistency from survey to survey.
    
    The different types of questions provided by eSurveysPro are as follows:
    
        Single Select: When you want respondents to choose just one alternative, 
		use a single select question. No "ties" are allowed and the respondent can only 
		pick only one option. Single select questions are appropriate when:
    
    
        - Each choice criterion is clearly stated.
 
        - The criterion actually defines a single category.
 
        - The difference between each category is relevant to your research objective.
        
 
    
    
        A few examples of single select questions are yes-no, select best that applies, 
		or preference scales. You can use single select questions for a variety of 
		purposes; such as filtering the respondents based on their answers, 
		prioritizing respondents, or asking follow up questions based on the answer 
		selected. Single select questions are ideal when you want to conduct 
		specialized data analysis such as Simple Regression or Multiple Regression 
		analysis.
    
    
        With eSurveysPro, it's easy for you to select whether response options are 
		displayed vertically, horizontally, in columns, or in a pull-down menu. Single 
		select questions can be used as the basis for skip groups, which take 
		respondents to the next question based on their previous response. Skip groups 
		are especially useful if you need to get further clarification on a response, 
		if certain questions are only appropriate for certain sets of respondents or if 
		you want to eliminate respondents through qualifying questions early in the 
		survey.
    
    
        Multiple Select: Multiple select (or multiple choice) questions allow 
		respondents to choose several different responses to a specific question. This 
		question format is very common because of its simplicity and versatility. 
		Multiple select questions are ideal for mutually exclusive response categories, 
		where the concepts do not overlap, and should not be used to gather numeric 
		data. When the answers can be expressed as numbers, a numeric response question 
		should be used, allowing respondents to record an exact number. Use multiple 
		select questions to gather all the possible and relevant responses to your 
		question, especially when you want to focus on particular categories or compare 
		across categories. For instance, you want to know which radio stations a 
		respondent listens to. Since many respondents may listen to several, you can 
		use a multiple select question. In your data analysis, you can assess the 
		demographic results based on each radio station, or each set of radio stations. 
		You can also identify the other stations respondents listen to in addition to a 
		specific station.
    
    
        eSurveysPro allows you to control how responses are displayed and require that 
		respondents select a certain number of items (e.g., "select the two most 
		important factors.").
    
    
        Open-ended questions: These questions are commonly knows as unstructured 
		or qualitative questions, and allow respondents to enter alphanumeric 
		responses. eSurveysPro offers limited and unlimited open-ended questions. 
		Limited text questions require the respondent to provide a brief answer, 
		whereas the unlimited text questions allow users to enter as much text as they 
		want. Open-ended questions may be used as totally independent questions or to 
		follow-up on structured or close-ended questions to collect additional 
		information or clarification. Unlimited text questions are helpful when they 
		are independent questions that require a higher amount of input from the 
		respondents. Whereas limited text questions are more suitable for follow-up 
		questions that require little additional information, or structured information 
		such as a telephone number, e-mail address or customer ID.
    
    
        Unlimited text questions may produce as many different responses as there are 
		respondents in the sample. To make sense of this data, beyond just reading each 
		response, it is helpful to group answers into categories so that you can 
		measure results quantitatively. This process can be very time-consuming, 
		especially with a lot of responses, so minimizing the number of unlimited text 
		questions you use in each survey is ideal.
    
    
        Numeric Value: The principal advantage to using a numeric value format is 
		that you obtain an actual number from each respondent. This is especially 
		valuable in measuring central tendency and median. If you need to analyze real 
		numbers, this format is preferable to single or multiple select questions, 
		where your analysis would be limited to response frequency for specified 
		ranges.
    
    
        By using eSurveysPro, you can specify a numeric range into which responses will 
		fall. When analyzing your data, eSurveysPro automatically calculates the mean 
		(average) and median (middle point) for each numeric value question, and lets 
		you select the step value in which the graph reports the data. This graph gives 
		you a quick snapshot of the distribution curve.
    
    
        Matrix format: eSurveysPro provides two types of matrix questions: single 
		select and multiple select. Matrix questions are best used when you want to 
		group questions with the same set of responses, such as in a Likert scale. The 
		single select format is most commonly used to rank multiple items on the same 
		scale, and is helpful in obtaining people's position on certain issues or 
		conclusions. The multi-select matrix format captures a higher number of data 
		points for each category, allowing respondents to choose several answers. You 
		can look at the sample provided below in order to get a better understanding of 
		multi-select matrix.
    
    
        eSurveysPro presents all of the results from each Matrix question in one stacked 
		bar graph, so you can compare the data sets to each other easily. Then each 
		category is graphed individually.
    
    
        Rank Order: A rank order question allows respondents to state their 
		preferences from a list of items. A ranking order question obtains not only the 
		most preferred items, but also the sequence of the remaining items, so you can 
		measure the relationship or importance between them. This type of data is very 
		useful while conducting conjoint analysis, where you look at the preferences of 
		specific respondents. Or you can use multiple rank order questions to conduct 
		correspondence analysis, where you can quantify and compare different sets of 
		perceptions.
    
    
        Date Format: This question lets you specify how the date should be 
		entered. It allows you to incorporate pre-field and post-field text. This 
		question is also used as a way to validate your data. You would not need to add 
		a question about the current date since eSurveysPro automatically assigns date 
		and time values to each response as it is taken so that you can compare results 
		over time.
    
    
        HTML Snippet: eSurveysPro supports the ability to insert HTML code 
		between questions. You can enter any HTML directly into the text area of the 
		dialog. It allows you to add section headings, special directions, images, 
		sounds, animations, tables or other HTML features.
    
    
        Hidden Fields: If you have data that you want to place into your survey 
		that you do not want to user to type in, the Hidden Field is the best solution. 
		Using the hidden field values can be passed in on the address of the survey as 
		parameters. This may be a trouble ticket number, a customer ID, employee ID, 
		etc. When you create a hidden field (or any question within eSurveysPro for 
		that matter) it is assigned a unique value within the survey. Using this method 
		you can pre-populate values into your survey that can be used to filter 
		responses.
    
    Data Validation
    
        Data validation lets you define what type of data you want entered in a cell and 
		how it should be entered. For example, you can allow entry of a letter grade 
		with only the letters A through F. With eSurveysPro, you can set up data 
		validation to prevent users from entering data that isn't valid, or allow 
		invalid data but check for it after the user is finished. By doing this, you 
		will ensure that your surveys are completed properly.
    
    
        eSurveysPro lets you designate the following types of valid data for your 
		survey:
    
    
        - Text validation: Designate the format in which the respondent must enter text 
		data. For example you can require that respondents enter their social security 
		number as either 999999999 or as 999-99-9999.
 
        - Length: Set the minimum and maximum number of characters that can be used in a 
		limited text response.
 
        - Numeric: Set a minimum and maximum value for numeric fields.
 
        - Date: Set a format in which the respondent must enter date information.
 
        - Data Block: Designate "Sum-to" amounts so that the total of the numeric entries 
		add up to an exact number.
 
        - Required Responses: Identify specific questions that respondents must answer. 
			Be careful when using both required responses and skip groups: if you set one 
			of your required response questions within a skip group, respondents who 
			skipped over that question will be returned to it during validation after they 
			press "Submit".
        
 
    
    
        With current, accurate data at your fingertips by using the right types of 
		questions and validating you data, you can make winning decisions about the 
		programs that you implement. eSurveysPro provides you with a list of question 
		types, question library as well as data validation features that you can use to 
		ensure that your data is accurate.
