IQ, EQ and aptitude tests: what each one measures
IQ tests, EQ questionnaires and employer aptitude tests sample different things and are scored differently. What each measures, and which kind ours are.
In short
An IQ test estimates general cognitive ability against a population norm and is administered by a professional. An aptitude test, the kind employers use, samples specific skills such as numerical or logical reasoning under time pressure and is scored against other applicants or a norm group. EQ is usually measured by self-report questionnaires about emotional habits, which is a different kind of measurement altogether. MyTestAtlas reasoning routes are practice in aptitude-style formats; its questionnaires are self-report reflections.

Intelligence tests
An intelligence test is a battery of subtests, verbal, spatial, working-memory and speed among them, administered one to one by a trained professional and scored against a national norm sample. The headline IQ is a composite; the report also gives index scores and confidence intervals. Its purpose is assessment: educational planning, clinical questions, research.
Aptitude tests
Aptitude tests, often called psychometric or cognitive-ability tests in hiring, are shorter and usually timed. They sample specific skills the employer cares about, such as numerical reasoning from tables, verbal reasoning from passages, or abstract reasoning from figure sequences. Scores are compared with other candidates or with a norm group of previous applicants, and time pressure is part of what they measure. Practising the formats is legitimate and makes a difference because the formats themselves are unfamiliar to most people.
Emotional intelligence
EQ or emotional intelligence is measured in two different ways. Ability-based tests present emotional situations with right and wrong answers; trait-based questionnaires ask people to rate their own emotional habits. Most online EQ tests are the second kind, which means they measure self-perception, and their results are not comparable with an IQ. That does not make them useless: a self-report profile can be a good prompt for reflection if it is labelled as such.
Which kind each MyTestAtlas route is
The reasoning routes under this hub offer untimed practice in familiar aptitude formats, with results by question type and answer explanations. The personality, focus and ADHD routes are self-report reflections, with patterns shown within each test's own range.
