Morphology
chi-square + statistic
The headword contains the transparent element 'statistic', so a B1 learner who knows that word can infer this is some numerical measure. However, 'chi-square' is a technical label (involving a Greek letter and a mathematical operation) whose specific function as a goodness-of-fit/independence test is not derivable from the parts without prior statistical knowledge. Because the expression partly signals its class but not its specialized meaning, it is only partially transparent.
Etymology
Chi-square statistic comes from the Greek letter chi χ and the fact we square the differences between what we see and what we expect. Because the test adds up those squared differences, the name helps you remember it is a single number used to check if data match a 'guess'.
