Sine Rule :: Cosine Rule :: Future Value :: the amount of money in the future that an amount of money today will yield, given prevailing interest rates Trapezoidal rule :: Limit of reading :: smallest unit on the measuring instrument also known as precision. Absolute error :: ½ × limit of reading (maximum value) Interquartile Range (IQR) :: the difference between the first quartile and third quartile. Q3 - Q1 standard deviation :: a measure of the spread of data about the m...

addition rule - a mathematical rule used to calculate the probability of the union of events alpha - The probability of rejecting the null hypothesis when, in reality, it is true. Alternative hypothesis - Designated H1, this hypothesis represents the opposite of the null hypothesis and holds true if the null hypothesis is found to be false. The alternative hypothesis always states the population parameter is <, not equal (=/), or > a specific value. bar chart - A chart that displays q...

Department of Mathematics and Natural Sciences Shape of the Distribution 1/1 Measures of Shape Skewness measures the deviation from the symmetry. SK = 3(µ median) (1) SK = 3(¯x median) s (2) Example The scores of the students in the Prelim Exam has a median of 18 and a mean of 16. What does this indicate about the shape of the distribution of the scores? Math031 - Mathematics in the Modern World 2 Boxplot A boxplot is also called a box - and - whisker plot.

Data point - Observation/record of (perhaps multiple) measurements for a single member of a population or data set. In the standard tabular format, a row of data. Bayesian Information criterion (BIC) - Model selection technique that trades off model fit and model complexity. When comparing models, the model with lower BIC is preferred. Generally penalizes complexity more than AIC. 1-norm (rectilinear distance, Manhattan distance) - Think of distances in blocks E (|xi - yi|) 2-norm (euclide...
