What is Data Interpretation?

Signs it is missing

Competencies are easier to spot by their absence. These are observable behaviours, not personality judgements — each one is something a colleague could describe from memory.

• —Quotes a percentage from a chart without being able to say what it is a percentage of.
• —Reads a rising line as a rising rate when the axis is cumulative, so a slowdown is reported as growth.
• —Pulls a total row into a per-segment comparison, which double-counts and is invisible once the slide is built.

Evidence to look for

You cannot interview for an ability. Asking somebody whether they are good with numbers, or careful with detail, measures their self-image and their confidence, and both are poor proxies. What an interview can do is send you to the work. Each prompt below points at something the person actually produced — the evidence is in the artefact, not in the answer.

1. A dashboard they use weekly: ask what each of two similar-looking figures on it is a share of, and whether the filters are the same.
2. A slide they built from somebody else's extract — check whether the filter applied to the source is stated anywhere on it.
3. A trend they reported: ask what would have to be true for the trend to be an artefact of the period chosen.

These are work-sample and observation prompts written for this page. They are deliberately not items from a live AssessAll instrument — published items stop measuring anything.

How to develop it

The development moves AssessAll puts in a growth plan when this competency is a person's priority area. Each is small enough to start this week.

• →Before touching the questions, spend 20 seconds stating what the table measures and in what units.
• →Practise estimating answers to one significant figure first — exact computation second.
• →Study the classic traps deliberately: percentage-of-what, base-year changes, and mixing shares with absolutes.

What measures data interpretation on AssessAll

Every form below reports a band for this competency. Item counts and time limits are the configured values, published here because they are the two numbers that decide what a score means and the two that vendors most often leave off a product page — a form with 20 items in 10 minutes and a form with 20 items in 25 minutes are not measuring the same thing.

Seconds per item is arithmetic on the two published columns, not a separate claim. Read it as the working pace the form assumes: under about 45 seconds an item, pace is part of what is being measured whether or not the product says so. See speeded test for why that distinction changes how the score should be read.

Often confused with Numerical Reasoning

How AssessAll measures it

Data Interpretation is not measured by a single question. Responses across an assessment map to the competency, roll up into a 0–100 score, and are interpreted against the four anchors above. Because every AssessAll assessment speaks the same competency language, results from different instruments accumulate into one profile rather than a pile of unrelated scores.

Aptitude items are multiple-choice and machine-scored against a key, so the band is reproducible and the whole form can be sat in under half an hour. That is the trade: an ability score is cheap, fast and comparable, and it tells you what somebody can work out — not what they will choose to do, which is what the behavioural competencies are for. Read one band beside the other rather than either alone, and browse the assessment catalogue or the store for the forms above.
