If you have questions about your rights or complaints about the research, contact the UNL Institutional Review Board (IRB) at (402) 472-6965 or irb@unl.edu.
Purpose: The purpose of this research is to understand how we perceive statistical graphics and how accurately we can read information from charts represented in different ways.
Time: This survey should take less than 20 minutes to complete.
Risks and Benefits
Quick Summary:
We are not collecting any data which can be traced back to you during this study.
We will publish the dataset from this survey in full online to ensure that other researchers can see how we obtained our results.
Stat 218 students: You will be given a code at the end of the study to prove you completed the survey. You do not have to agree to allow your responses to be used for research purposes in order to get the code. This code will not be associated with your responses to this survey.
Reasonable steps will be taken to protect the privacy and the confidentiality of your study data; however, in some circumstances we cannot guarantee absolute privacy and/or confidentiality.
Your responses to this experiment will be stored in de-identified form and will not be able to be traced back to you. Because this data is anonymous, it will be stored and maintained in accordance with university policies for low-risk data.
Data Sharing and Publication
Data from this experiment may be published along with computer code describing the analysis and any study results in order to ensure the reproducibility of any analyses performed as part of this research. This data is anonymous - it cannot be traced back to you. The researchers will also archive the data for this study on the UNL Data Repository, where it will be preserved indefinitely and made publicly available.
You can decide to not allow your responses to be used for research purposes by declining to participate in this research study (select “I do not agree” below). This will prevent your data from being recorded and used for research, but you will still be able to see the study questions and provide responses.
You can decide not to be in this research study, or you can withdraw at any time before or during the study for any reason. Deciding not to be in this research study or deciding to withdraw will not affect your relationship with the investigator, the University of Nebraska-Lincoln, or your Stat 218 instructor. You will not lose any benefits to which you are entitled.
If you are taking this survey as part of Stat 218, you can decline to have your data recorded by selecting “I do not agree” and still obtain a participation code by completing the survey questions. The only difference is that your data will not be saved or used for research.
You are voluntarily making a decision whether or not to participate in this research study. By clicking on the I Agree button below, your consent to participate is implied. You should print or save a copy of this page for your records.
Thank you for participating in our experiment on perceptual judgments in different graphical mediums. You will see a series of 15 charts in this experiment On each screen, you will see either a rendered chart (in 2D or 3D), or a prompt to choose a 3D printed chart from your kit.
Before you start, please enter your kit number so that we know what charts you have.
If you are instructed to use a 3D chart, you will pick one of the charts from your kit and select the ID code on the bottom of the chart. Otherwise, use the graph which shows up on the screen.
You will be able to use your mouse to interact with 3D plots shown on your screen.
First, select which marked bar, circle or triangle, is smaller. Then, visually estimate how big the smaller bar is in comparison to the larger bar.
When you are ready, click 'Begin'
Your response has been submitted. Please return the graphs to the kit bag and reload the page to reset the application for the next user.
