Assignee: Unassigned · due 14 days after project start · takes 7 days
#3Data QualityHighTo Do
Define what it means for data to be a low-bias representation of the phenomenon—completeness, correctness, reliability, representativeness—and why it sets the ceiling on everything you can conclude.

Assignee: Unassigned · due 217 days after project start · takes 14 days
#21Randomization and Control of AssignmentMediumTo Do

Assignee: Unassigned · due 231 days after project start · takes 7 days
#22Model Complexity and FlexibilityHighTo Do
Model capacity—parameters, features, degrees of freedom—as a dial you actively set via regularization and constraints, and how that dial governs the bias-variance tradeoff.
Assignee: Unassigned · due 238 days after project start · takes 14 days

Assignee: Unassigned · due 252 days after project start · takes 7 days
#24Overfitting and Capitalization on ChanceHighTo Do

Assignee: Unassigned · due 259 days after project start · takes 14 days
#25Resampling and Model ValidationHighTo Do
Estimate how a model will perform on data it hasn't seen, using cross-validation, the bootstrap, and permutation tests instead of leaning on distributional assumptions. You get the logic for choosing among them and the traps that silently inflate your reported accuracy.
Assignee: Unassigned · due 273 days after project start · takes 14 days
#26Latent Variables and Measurement ModelMediumTo Do
Model constructs you cannot observe directly by exploiting the shared covariance among their indicators, and how factor, SEM, and IRT models separate true signal from measurement error. You get the reasoning for when a latent structure is warranted.
Assignee: Unassigned · due 287 days after project start · takes 7 days
#27Item Parameters and IRT ModelingLowTo Do

Assignee: Unassigned · due 297 days after project start · takes 7 days
#29Causal Reasoning and Identification StrategyHighTo Do

Assignee: Unassigned · due 325 days after project start · takes 14 days
#32Construct ValidityMediumTo Do
Build the evidence network showing your indicators actually capture the theoretical construct you claim, and how to detect systematic distortion that reliability alone won't reveal.
