Reference excerpt

Leyla Kheradmand Mohadjer is an American statistician who works as a vice president, senior statistical fellow, and associate director of the statistical staff at Westat. She is an expert in survey methodology, total survey error, quality control, and participation bias, and has led the statistical efforts of the Programme for the International Assessment of Adult Competencies and the Programme for International Student Assessment (both of the OECD), and the National Health and Nutrition Examination Survey of the National Center for Health Statistics. Mohadjer earned a master's degree and, in 1985, a doctorate in statistics from George Washington University. Her dissertation was The efficiency of the normal discriminant analysis compared to the logistic regression for the prediction criterion. She was elected as a Fellow of the American Statistical Association in 2007. She is also an Elected Member of the International Statistical Institute.

Worked examples

Example 1 — a first encounter with Leyla Mohadjer

Start with the simplest possible case. Write down what Leyla Mohadjer claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In mathematics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Leyla Mohadjer before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Leyla Mohadjer ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Leyla Mohadjer

In research: Leyla Mohadjer appears in mathematics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Leyla Mohadjer in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Leyla Mohadjer is common in secondary-school and first-year university syllabi. It links to neighbouring topics American statisticians, American women statisticians, Elected Members of the International Statistical Institute, so understanding it makes those chapters shorter.
In everyday life: Look for Leyla Mohadjer outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
