The document provides guidance on designing effective questionnaires for research. It discusses what a questionnaire is, its objectives and advantages and disadvantages. It outlines the key steps in questionnaire design which include determining what information is needed, deciding on the type of questions, evaluating question content, determining question order and wording, and pre-testing the questionnaire. It also describes different types of questions like open-ended and closed-ended questions and how to overcome respondents' inability or unwillingness to answer. The document stresses the importance of carefully designing the form, layout and order of questions.
Questionnaires is one of the most popular tool of collecting data
They provide a convenient way to gathering information from a target population. A questionnaire is a planned self-reported form designed to elicit information though written or verbal responses of the subjects.

Questionnaire, interview, observation and rating scale zunaira rafiq
In writing about your research when you have completed the project you need an explanation of your methodology so that others can understand the significance of what you have done and make sense of how it all worked. The methodology piece says why you did what you did. It also enables you to write about what you did not do and why, and about the weaknesses or limitations of your project as well as its strengths. Every research has a limitation of some sort and it is perfectly acceptable to identify the weaknesses of your own study.

Levelwise PageRank with Loop-Based Dead End Handling Strategy : SHORT REPORT ...Subhajit Sahu
Abstract — Levelwise PageRank is an alternative method of PageRank computation which decomposes the input graph into a directed acyclic block-graph of strongly connected components, and processes them in topological order, one level at a time. This enables calculation for ranks in a distributed fashion without per-iteration communication, unlike the standard method where all vertices are processed in each iteration. It however comes with a precondition of the absence of dead ends in the input graph. Here, the native non-distributed performance of Levelwise PageRank was compared against Monolithic PageRank on a CPU as well as a GPU. To ensure a fair comparison, Monolithic PageRank was also performed on a graph where vertices were split by components. Results indicate that Levelwise PageRank is about as fast as Monolithic PageRank on the CPU, but quite a bit slower on the GPU. Slowdown on the GPU is likely caused by a large submission of small workloads, and expected to be non-issue when the computation is performed on massive graphs.

The Building Blocks of QuestDB, a Time Series Databasejavier ramirez
Talk Delivered at Valencia Codes Meetup 2024-06.
Traditionally, databases have treated timestamps just as another data type. However, when performing real-time analytics, timestamps should be first class citizens and we need rich time semantics to get the most out of our data. We also need to deal with ever growing datasets while keeping performant, which is as fun as it sounds.
It is no wonder time-series databases are now more popular than ever before. Join me in this session to learn about the internal architecture and building blocks of QuestDB, an open source time-series database designed for speed. We will also review a history of some of the changes we have gone over the past two years to deal with late and unordered data, non-blocking writes, read-replicas, or faster batch ingestion.

Enhanced Enterprise Intelligence with your personal AI Data Copilot.pdfGetInData
Recently we have observed the rise of open-source Large Language Models (LLMs) that are community-driven or developed by the AI market leaders, such as Meta (Llama3), Databricks (DBRX) and Snowflake (Arctic). On the other hand, there is a growth in interest in specialized, carefully fine-tuned yet relatively small models that can efficiently assist programmers in day-to-day tasks. Finally, Retrieval-Augmented Generation (RAG) architectures have gained a lot of traction as the preferred approach for LLMs context and prompt augmentation for building conversational SQL data copilots, code copilots and chatbots.
In this presentation, we will show how we built upon these three concepts a robust Data Copilot that can help to democratize access to company data assets and boost performance of everyone working with data platforms.
Why do we need yet another (open-source ) Copilot?
How can we build one?

2. What is a Questionnaire?
A Questionnaire is a formalized set of questions for
obtaining information from respondents.
oIt must translate the information needed into a set of specific questions that the
respondents can and will answer.
oA questionnaire must uplift, motivate and encourage the respondent to become
involved in the interview, to cooperate, and to complete the interview.
oA questionnaire should minimize response error.
Objectives
3. Questionnaire Advantages
o Low cost in terms of time, labor, and wealth
o Free from interviewer bias
o Respondents have adequate time to think through their answers
o Respondents who are not easily approachable can also be reached conveniently
o Large samples can be used, or the field of inquiry is wide
4. Questionnaire Disadvantages
o Low rate of return
o Respondents need to be educated person and cooperative
o Inbuilt inflexibility (Supplementary questions can not be asked as questions are fixed)
o Possibility of ambiguous replies or omission of items
o This method is slow
o Its response is uncertain
o If the questionnaire is challenging, it may not be responded
5. Questionnaire Design Process
Specify the
information needed
Specify the Type of
Interviewing Method
Determine the
content of Individual
Questions
Design the Question to
overcome the
respondent’s Inability
and Unwillingness to
answer
Decide the question
structure
Determine the
question wording
Arrange the
questions in proper
order
Identify the Form
and Layout
Reproduce the
Questionnaire
Eliminate Bugs by
Pre-Testing
6. Steps in Questionnaire Design
1. Determine what information is required:
o Translate research objectives into a research question.
o How Variables are going to be measured.
o Think through the techniques that will give meaning to the data.
2. What type of questionnaire to be used in the survey:
o Personal interview with a questionnaire
o Telephone interview
o Mail Survey
o Observation method
7. Steps in Questionnaire Design
3. Evaluate the question content:
o Does the respondent understand the question
o Does the respondent have the information desired?
o Will respondent give the information
o Are several questions needed instead of one
o Determine question/response format
o Should we use ordinal scaled questions?
o Should we use multiple choice questions?
o Decide on the wordings of the questions.
o Avoid leading questions
o Avoid unbalanced questions
o Avoid barreled questions
o Avoid questions that involve estimation
8. Steps in Questionnaire Design
4. Decide on question sequence and logical order:
o Leading Questions
o Qualifying Questions
o Warm-up Questions
o Specific Questions
o Demographic Questions
5. Determine the physical characteristics of the form.
6. Pretest, revise and final the form.
9. Types of Questions
Open-ended
oRespondent can answer in own words
oNo preset choices
oUsed where the range of answers is very wide or unknown
oUsed to expand on or explain answers to previous questions
oTime-consuming to code and data input
oAvoid using too many open-ended questions
oAvoid using it in the end
10. Types of Questions
Closed-ended
oRespondent is made to choose the answer from predefined responses.
oMost common forms are;
• Dichotomous
• Multiple Choice
• Scale or Rating
• Ranking
• Quantity
11. Overcoming Inability to answer
oA “Don’t Know” option appears to reduce uninformed responses without reducing the response
rate.
oRespondents may be unable to articulate certain types of responses, e.g., Describe the
atmosphere of a departmental store.
oRespondents should be given aids, such as pictures, maps or descriptions to help them
articulate their responses.
oMost respondents are unwilling to devote a lot of effort to provide information.
12. Choosing Questions Wording
oDefine the issues in terms of who, what, when, where, why, and way.
oUse ordinary words. Words should match the vocabulary level of the respondents.
oAvoid ambiguous words: usually, normally, frequently, often regularly, etc.
oAvoid implicit alternatives that are not explicitly expressed in the options.
oUse positive or negative statements.
oRespondents should not have to make generalizations or compute estimates.
13. Determine the Order of Questions
oOpening questions should be interesting, simple, and non-threatening.
oQualifying questions should serve as the opening questions.
oBasic information should be obtained first, followed by the classification, and, finally,
identification information.
oDifficult, sensitive, or complex questions should be placed late in the sequence.
oQuestions should be asked in logical order.
oBranching questions should be designed carefully to cover all possible contingencies.
14. Form and Layout
oDivide a questionnaire into several parts.
oThe questions in each part should be numbered, particularly when branching questions are
used.
oThe questionnaires should preferably be pre-coded.
oThe questionnaires themselves should be numbered serially.
