What is a construct?
A construct is a defined attribute you cannot photograph directly: anxiety, spatial span, processing speed. Tests are fallible indicators of it. Latihan — bukan IQ klinis.
How is construct validity shown?
Convergent correlations with similar tests, discriminant gaps from unlike tests, factor structure, and experimental manipulations. One viral quiz is none of that. Latihan — bukan IQ klinis.
Is face validity enough?
No. Looking like an IQ item is marketing. Construct work is slower and public in manuals and papers. Latihan — bukan IQ klinis.
Can a game have a little construct meaning?
It can illustrate a task class. Illustration is not a claim that your hit count is “g.” Latihan — bukan IQ klinis.
What threatens construct validity here?
Device lag, cheating, language, practice, and tiny trial counts. Those are features of a browser toy. Latihan — bukan IQ klinis.
What should I try?
Backward letter span lite and pattern matrices lite sit on different task families. Treat both as practice, not as a construct battery. Latihan — bukan IQ klinis.

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. Latihan — bukan IQ klinis.
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. Latihan — bukan IQ klinis.
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. Latihan — bukan IQ klinis.
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. Latihan — bukan IQ klinis.
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. Latihan — bukan IQ klinis.
