Mathematics and Data Interpretation Flashcards

Vocabulary flashcards covering BODMAS, factors and multiples, basic statistical measures (range, mode, median, mean), changing fractions using shared multiples, and decomposing 2D shapes.

B.O.D.M.A.S

An order of operations framework used for simplifying calculations.

Common Factor

A factor shared by two or more numbers, such as $1$, $2$, $3$, and $6$ for the numbers $12$ and $18$.

Highest Common Factor (HCF)

The largest number on a shared list of common factors between two or more numbers, which is $6$ for the numbers $12$ and $18$.

Common Multiple

A multiple shared by two or more numbers, such as $12$, $24$, and $36$ for the numbers $4$ and $6$.

Least Common Multiple (LCM)

The smallest number on a shared list of common multiples between two or more numbers, which is $12$ for the numbers $4$ and $6$.

Statistics

The branch of study that helps us to interpret data.

Range

The difference between the highest and lowest values in a dataset, calculated as $(23 - 13) = 10$ for the sample scores $13, 15, 15, 16, 16, 16, 16, 17, 17, 19, 19, 19, 23$.

Mode

The value in a set of data that occurs the most often, such as $3$ for the number set $7, 5, 3, 8, 6, 3, 3$.

Median

The middle number in a data set when the numbers are ordered, such as $5$ for the ordered set $3, 3, 3, 5, 6, 7, 8$.

Mean

The average calculated as $\text{Mean} = \frac{\text{total}}{\text{number of items}}$, such as $\frac{35}{7} = 5$ for the numbers $7, 5, 3, 8, 6, 3, 3$.

Fraction Equivalent Transformation

The procedure of identifying a shared multiple for the bottom numbers (denominators) and multiplying both the top and bottom by the same factor so the fraction remains equal.

Decomposing 2D Shapes

The process of taking one shape and cutting or dividing it to find smaller hidden shapes within it.
