Analysis of Survey Data: 101 and Beyond Brandon Yong Mon, 10/28/2024 - 10:42

Though the workshop will not go into mathematical details and proofs, it will provide some reasoning and intuition behind the key formulas used in survey sampling. It will also look at various examples using the statistical software SAS (free to students, faculty and staff at the University of ��ݮ��Ƶ). In addition to illustrating basic data analysis techniques, those examples aim to provide guidance on some of the pitfalls of analyzing survey data. Part 4 is a practical hands-on opportunity for participants to conduct basic data analysis using SAS on their own laptop.

Participants are not expected to know about survey sampling, but should have some knowledge of basic statistical concepts (ideally have taken at least one course in statistics).

This two-day workshop will be held at DC 1568.

Registration is free and open to all University of ��ݮ��Ƶ faculty, staff, and students (both graduate and undergraduate).

Workshop Outline

Part 1: Dec 4th, 9:30 AM – 12:00 PM

Introduction (vocabulary, notation, and basic concepts)
Sampling designs and selection probabilities
Introduction to sampling weights

Part 2: Dec 4th, 1:00 PM – 4:00 PM

Estimating a population total (i.e., Horvitz-Thompson estimator)
Estimating a population mean (i.e., Hajek estimator)
Estimating a population proportion
Selection bias and other non-sampling errors
Rao-Scott Chi-Square test

Part 3: Dec 5th, 9:30 AM – 12:00 PM

Linear and logistic regression using survey data

Part 4*: Dec 5th, 1:00 PM – 3:30 PM

Introduction to SAS OnDemand for Academics, basic SAS commands and procedures
Using the SURVEYFREQ and SURVEYMEANS procedures
Using the SURVEYREG and SURVEYLOGISTIC procedures
Basic data manipulations, better looking output (e.g., formats, titles, footnotes) and ODS

* In Part 4, participants will conduct basic data analysis using SAS OnDemand for Academics (free to students, faculty and staff at the University of ��ݮ��Ƶ). Hence, participants must bring their own laptop and register. Installation instructions will be provided, but in person help will also be available from 4:00 to 4:30 pm on day 1.

An Introduction to Linear Regression Joslin Goh Mon, 01/29/2024 - 11:00

Linear regression models, also known as linear models, are widely used in various applications and research. It is one of the most popular models out there because of its simplicity and easy interpretation.

This workshop will provide participants with an introduction to simple and multiple linear regression. Topics covered in this workshop include the regression models, model assumptions, interpretation of coefficients, significance testing, interactions between variables and the use and interpretation of dummy variables. Model-checking methods such as residual plots and collinearity diagnostics will also be covered. Several methods for model selection will be included.

Registration is free and open to all University of ��ݮ��Ƶ faculty, staff and graduate students.

There will be both lecture and hands-on computer work using R. Participants are encouraged to bring their own laptop with R and RStudio installed.

Survey Programming in Qualtrics

Brandon Yong — Wed, 24 Jan 2024 17:25:05 +0000

Survey Programming in Qualtrics Brandon Yong Wed, 01/24/2024 - 12:25

Learn how to use Qualtrics to create and launch a survey. The goal of this workshop is to provide an overview of the whole process along with some hands-on exercises. The workshop will start with instruction on how to build a survey, then will cover getting it ready for the field, and finish with showing users how to distribute, monitor, and extract their data.

This in-person workshop will be held at DC 1568 (inside the DC library). The workshop includes some hands-on practice. Participants will need to bring their own laptops for the survey programming exercise.

Please ensure to set up your Qualtrics account (free to you through the University's license) prior to the workshop. Instructions for setting up your account can be found in the U��ݮ��Ƶ knowledge base.

This workshop will cover:

Getting started with Qualtrics
Building a survey (including a survey programming exercise)
Preparing a survey for the field
Testing a survey
Launching and monitoring a survey
Closing a survey
