How do you get a stanine from a raw score?
Through a norm table for that test and age. No universal web converter exists for our toys. Luyện tập — không phải IQ lâm sàng.
Stanine versus percentile?
Percentiles keep more ranks. Stanines bunch people. Neither is a Wechsler IQ unless the manual says so. Luyện tập — không phải IQ lâm sàng.
Is 9 gifted?
Band 9 is the top of that nine-band chart, not a legal gifted definition. Districts use their own rules and licensed tools. Luyện tập — không phải IQ lâm sàng.
Why would anyone use a coarse band?
To discourage over-interpreting one-point changes. Irony: people then treat 9 as a trophy. Luyện tập — không phải IQ lâm sàng.
Can I average stanines across games?
No. Different toys, no joint norms. Averaging is a new made-up number. Luyện tập — không phải IQ lâm sàng.
What to try?
Letter span lite is a raw span count. Leave it as a count. Luyện tập — không phải IQ lâm sàng.

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. Luyện tập — không phải IQ lâm sàng.
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. Luyện tập — không phải IQ lâm sàng.
What is criterion validity? →What is content validity?
Content validity is whether the item set covers the skill or knowledge you claimed. A spelling test with only the letter Q is a coverage failure. Shape-span lite samples a tiny visuospatial sequence. It does not cover “all spatial intelligence.” Experts, blueprints and reviews build content arguments. A weekend hackathon does not. Luyện tập — không phải IQ lâm sàng.
What is content 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. Luyện tập — không phải IQ lâm sàng.
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. Luyện tập — không phải IQ lâm sàng.
