The Threats To Statistical Conclusion Validity - Measurement Error Video
In this video, I talk about measure error which is a statistical conclusion validity problem. Threats to statistical conclusion validity occurs when when draws inferences based on statistical tests and the statistical tests are misrepresenting the actual causal relationship.
Measurement error is quite common in the social sciences as we measure imperfect constructs. We often do not have a good understanding of the construct itself, and then you compound on top of that items that do not measure the construct well, and you can have problems with statistical conclusion validity.
Measurement error reduces the relationship between the variables of interest.
To reduce measurement error and to improve the statistical conclusion validity, I would suggest the following:
1. Keep constructs simple. Don’t force constructs.
2. Measure constructs in multiple ways, both with more methods and more items within each method.
3. Think in terms of ideal ways to test.
4. “Measure twice, cut once.”

David is a research professor of entrepreneurship, innovation, and business strategy, I discuss topics, such as behavioral science, strategy, innovation, and entrepreneurship, and apply these to my new peer proofreading and editing platform. Topics include the sharing economy, altruism, investing in technology, and bounded rationality. My favorite videos pertain to incentives, goal setting, and learning from failure to drive behaviors such as weight loss, stopping telemarketers, creating novel technologies, and creating new movements.
r3ciprocity.com: Peer proofreading and editing platform
A new platform where you can earn credits by editing other people's documents. Use these credits to have your own work edited. If you do a good enough job, you can convert these credits to money.
The goal of the platform is to get people to 'pay it forward' and help other people out by creating incentives for people to give back.

About the Site 🌐
This site provides links to random videos hosted at YouTube, with the emphasis on random. 🎥
Origins of the Idea 🌱
The original idea for this site stemmed from the need to benchmark the popularity of a video against the general population of YouTube videos. 🧠
Challenges Faced 🤔
Obtaining a large sample of videos was crucial for accurate ranking, but YouTube lacks a direct method to gather random video IDs.
Even searching for random strings on YouTube doesn't yield truly random results, complicating the process further. 🔍
Creating Truly Random Links 🛠️
The YouTube API offers additional functions enabling the discovery of more random videos. Through inventive techniques and a touch of space-time manipulation, we've achieved a process yielding nearly 100% random links to YouTube videos.
About YouTube 📺
YouTube, an American video-sharing website based in San Bruno, California, offers a diverse range of user-generated and corporate media content. 🌟
Content and Users 🎵
Users can upload, view, rate, share, and comment on videos, with content spanning video clips, music videos, live streams, and more.
While most content is uploaded by individuals, media corporations like CBS and the BBC also contribute. Unregistered users can watch videos, while registered users enjoy additional privileges such as uploading unlimited videos and adding comments.
Monetization and Impact 🤑
