This powerful calculator enables you to plot and analyse graphs and their transformations, import data directly over USB, plot data charts and calculate statistics, calculate and visualise probability distributions, plot and solve graphs in 3D, calculate matrix and vector arithmetic, perform complex calculations not possible on a scientific calculator, calculate spreadsheets and recursive sequences, and whole host more. The Test mode on the fx-CG50 calculator is useful for performing hypothesis test questions. To explore it, find a normal distribution hypothesis test from any UK A-level mathematics exam syllabus and then go to Statistics Mode (MENU 2) and then F3 (TEST), F1 (Z), F1 (1-Sample) and F2 (Var) and input the relevant parameters from the question. If studying further Mathematics or Statistics A-level then there are several options here that are also useful (e.g. Chi-squared tests, t-tests, ANOVA tests etc. ).

The Normal distribution, also known as the Gaussian distribution, is an important continuous probability distribution that is widely used in statistics and probability theory. It’s bell-shaped and symmetric around its mean value, with most data clustered around the mean and decreasing towards the tails. It’s a versatile distribution that arises naturally in many real-world applications and is used to model various phenomena in fields such as finance, engineering, and social sciences. Even the difficulty level of a standard exam paper is maintained so that the marks scored by students are normally distributed. 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. Applications for CG50A can be made online in myAccountor the Revenue Online Service (ROS)by selecting: Additionally, you can find the values of the summary statistics quite easily for any lists of data that you have. Remember: The functionality keeps expandingAnother reason many teachers are interested in using the fx-CG50 is that it’s a lot better at displaying and calculating statistics than the fx-991ex. In Statistics mode, which is shortcut ”2” in Main Menu, there’s a whole range of features available to construct pie charts, bar charts, histograms and box plots (referred to as a MedBox on the device) lists of data. It’s very useful, as the device will draw these diagrams and graphs for you. If we take the box plots example, you can easily draw up to three of these and then compare them. The device also gives you access to the summary statistics. You can TRACE a point and find out for example, the median value. the lower quartile; or the smallest value in the list.

The history feature means you can do a calculation and then do another calculation with that answer. However, unlike on scientific calculators there is more than one line of input shown, meaning you can expand or amend a series of calculations further and even go off the screen – you can keep scrolling down, and you’re not limited to the space shown on the screen. Exploring graph mode More details on how to apply online are available in the Guide for Applicants (TDM 42-03-01a). Can an agent apply for CG50A for you? 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 life, as in exams, we can’t get rid of Stats – it’s everywhere. The fx-CG50 calculator is just the tool to tap into the world of Stats intuitively. It’s a powerful device with various statistical functions built into it. Summary statistics are elementary to calculate with the fx-CG50. The statistics mode can be accessed by pressing menu and 2.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. 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.

You would then use Graph Solve or G-SOLVE. The most common aspects you may want to explore on your graph include finding the root, it’s local maximum value or its local minimum value, where it is crossing the y-axis. or, if there are two functions drawn, where they cross each other. Getting started with calculations is fairly intuitive. When dealing with fractions, you can input fractions quite nicely using the default fraction button, which every calculator has. You can use S to D to interchange between fractions and decimal solutions.To solve this, students can go into Statistics mode (MENU 2) and then the binomial distribution menu (F5 (DIST), F5 (BINOMIAL), F2 (Bcd)) on the handset and enter the values, including the number of trials and probability of success. Other documentation may be required dependant on the application. What happens if you do not get a CG50A? Knowing these two views is useful because sometimes you may need a decimal because it’s asked for in a question, or sometimes you use the fraction because that’s an exact answer.
