Applications for CG50A can be made online in myAccountor the Revenue Online Service (ROS)by selecting: Example: Find all the summary statistics (Mean, Median, Mode, Standard Deviation etc. ) for 3,4,6 and 7 The 1-VAR option in the CALC mode of the fx-CG50 calculator is a statistical function used to calculate descriptive statistics for a dataset with a single variable, which is X here. It allows you to find basic statistical measures such as the mean, standard deviation, variance, minimum and maximum values, and quartiles.

For example, consider a random variable X which follows a binomial distribution with parameters n = 50 and p = 0.2. Here “n” is the number of trials, and “p” is the probability of success. Its notation can be written as X-B(50,0.2), and imaging the question asks to find P(X>9), which is the probability of X taking a value greater than 9. SolveN is an incredibly powerful tool that can be used to solve pretty much any equation with a numeric answer. To access it go into RUN mode (MENU 1) and then press OPTN and then F4 (CALC) and then F5 (SolveN)

In this article, James Davis, Head of KS5 Further Mathematics, Newstead Wood School, discusses the powerful statistics functionality of the fx-CG50 calculator. From mastering the different menus to confidently navigating the various modes, James guides you through the steps required to ensure your students are well-prepared to use the statistics functions on their calculators in any exam setting. Don’t be a Statistic said no Statistician ever… Binomial and normal distributions are two important probability distributions used in statistics and probability theory. When only two outcomes are conceivable for each trial and a fixed number of independent trials, the binomial distribution is frequently used. Conversely, the normal distribution is used to model continuous data that follows a bell-shaped curve. graphs, 20 graphing functions, spreadsheet function, statistical function, dynamic graphing, geometry, picture plot, integral graphing, pie & bar chart (in stat mode), graphing calculations, linear, quadratic and cubic equations, vector analysis, mathematical functions, square root, fractions, integration, complex functions, matrix algebra, linear equations, polynomial equations
