If slope is 2, slope of perpendicular line = – 1/2, Linear equation: y = mx + b [The slope-intercept formula is sometimes called the linear equation. The term ‘n1’ represents the size of the first sample, and the term ‘n2’ represents the size of the second sample that is being pooled with the first sample. Intellectus allows you to conduct and interpret your analysis in minutes. © 2020 Tutor.com / The Princeton Review - Not Affiliated with Princeton University. The term ‘Σ ( xi – x_bar )2’ represents the sum of the squared deviations of the scores from the sample mean. The term ‘sqrt’ used in this statistical formula denotes square root. Discusses Bayes' theorem in relation to mutually exclusive events and 2 ways to calculate the statement. Includes links to web pages that explain how to use the formulas, including sample problems with solutions. Statistics Solutions can assist with your quantitative analysis by assisting you to develop your methodology and results chapters. Perpendicular lines: The slopes of perpendicular lines are negative reciprocals. (adsbygoogle = window.adsbygoogle || []).push({});
, Mean: sum of the numbers ÷ amount of items in set, Median: middle number in set when items are in order, Mode: number that is most frequent in the set, Example data set: 1, 2, 3, 1, 4, 5, 2, 1, 7 [There are 9 items in the set.
