Who judges content?
Subject-matter experts and, for high-stakes tests, documented panels. You and a comment thread are not a panel. Übung, kein klinischer IQ.
Is more items always better coverage?
More can help if they are on-blueprint. Twenty clones of one trick are still one trick. Übung, kein klinischer IQ.
Achievement versus aptitude?
Content arguments differ: curriculum sampling versus cognitive-process sampling. Do not mix the labels. Übung, kein klinischer IQ.
Cultural content?
Vocabulary and clock-reading assume cultural clocks. That is a content and fairness issue, not a personality insult. Übung, kein klinischer IQ.
Can I skip a section I dislike?
On a licensed battery, skipping is a clinician decision. On this site, skip any toy. Neither skip is an IQ index. Übung, kein klinischer IQ.
What to try?
Mental clock lite and verbal analogies lite sample different domains. Neither is a content-valid IQ. Übung, kein klinischer IQ.
❓ Häufig gestellte Fragen
What is construct validity?
Construct validity is the argument that a score reflects a named idea — working memory, not “being clever in general.” It is built from theory, patterns of correlations, and failed rival explanations. A 20-trial number-Stroop lite can feel like control. Feeling is not a validity coefficient. This site never reports a licensed IQ. Übung, kein klinischer IQ.
What is construct validity? →What is criterion validity?
Criterion validity asks whether a score lines up with something you care about that is not the test itself — a later grade, a supervisor rating, or a Wechsler index. Concurrent means measured at the same time; predictive means later. A visual 2-back lite has no published criterion table. It is not an employment screen and not an IQ. Übung, kein klinischer IQ.
What is criterion validity? →What is a confidence interval?
A 95% confidence interval is a procedure: if you repeated the study under the same model, 95% of such intervals would cover the parameter. It is not the probability that this one interval magically contains the truth after you saw it. Licensed IQ manuals turn a standard error into a range around a scaled score. Digit-span lite does not. Treat any integer from this site as a toy count. Übung, kein klinischer IQ.
What is a confidence interval? →What is item response theory?
Item response theory (IRT) models each item: harder items need more of the trait for a 50% chance of success; discriminating items separate nearby people. Computerized adaptive tests pick the next item from that model. Pattern-matrices lite is a fixed original set. It does not estimate a theta with published item parameters. It is not an IQ. Übung, kein klinischer IQ.
What is item response theory? →What is a g-loading?
In a factor analysis of several tests, a general factor (g) can appear. A subtest’s loading says how much it shares that factor in that sample and battery. Matrices often load high; some speeded motor tasks load lower. A loading is not your worth. N-back lite is not a published g-loading table. This site does not output g. Übung, kein klinischer IQ.
