What is PCA? (5 key points) Principal Component Analysis is a statistical technique used for dimensionality reduction, crucial when dealing with high-dimensional data in machine learning. It works by transforming original variables into new ones, called principal components, which are linear combinations of the original variables. Key Points: 1. Principal Components: Principal components are the directions in the data that maximize variance. The first principal component captures the most...

A researcher wants to know if there was a relationship between student age and desire to complete a college degree. To answer this question, the researcher used a local community college as the sampling frame and then used stratified sampling to get a sample of students from 18 to 80 years old. Based on the information given, is there any potential bias in this study? a Yes, because the sampling frame does not match the intended population of the question. b Yes, because the sampling method ...

What does the ADDIE model stand for? - correct answer Analysis Design Development Implementation Evaluation What does SAM stand for? - correct answer Successive Approximation Model What does UbD stand for? - correct answer Understanding by Design What is the difference between ADDIE, SAM, and UbD? - correct answer ADDIE offers a stepwise process for design development. SAM was developed as a more rapid process. Both ADDIE and SAM are primarily focused on the learning objectives (LO)...
