BSAN160 Final Test Questions with Correct Answers How are the whiskers for maximum and minimum in a box plot determined? - Answer-Whiskers for maximum and minimum are derived from the Inter-Quartile Range and is 1.5 times the IQR Schema for Data Preparation - Answer-Data consolidation, Data cleaning, Data transformation, Data reduction Data Consolidation - Answer-Data preprocessing method that accesses and collects the data, selects and filters the data, integrate and unify the data (thr...

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. It is a graphical...

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...

Categorical Data correct answer: Assigns a unique value for each case, used to name or identify it Quantitative Data correct answer: A variable in which the numbers act as a numerical value, always have units Stem and leaf plot correct answer: Shows quantitative data values in a way that sketches the distribution of the data Ogive correct answer: a graph that represents the cumulative frequencies for the classes in a frequency distribution Histogram correct answer: Bar graphing ...
