This application allows you to calculate themean, variance and standard deviation in samples of small size.After each value press the button ENTER. To get the results,press the button ENTER with an empty value.Use the C button to clear the value that you are entering at themoment. If you press C again, the last value which has already beenentered it will be deleted.Press the N button to begin to introduce a new sample.

The Student t test is used for comparing themeans of two small samples (here, with sizes from 2 to 60).To enter or change a text or a value, press on it, introduce thenew text or value, and press again on it to make effective thechangeOnce data are been introduced, press button ONE TAIL or buttonTWO TAILS to obtain the results.Use TWO TAILS if your work hypothesis is validated with deviationsin any of the two directions.Use ONE TAIL if your work hypothesis is validated only in onedirection (p.e. You expect an improvement of patients after thetreatment).

The application generates random fractions todivide and you must enter numerator and denominator of thequotient.

The application allows you introduce andmodify data of a contingency table (2 x 2) and analyse therelationship between two ordinal or nominal dichotomous variables.The option "observed" shows the table of data introduced withmarginal totals.The option "expected" shows the table of expected data.The option "chi square" shows the table with observed data,expected data, differences, square differences and the quotientsbetween square differences and expected values which total sum isthe chi square estimated.If the value of chi square is high enough we can reject the nullhypothesis and say that probably the differences are significantand there is a relationship between the two variables.In the example you see when the application is installed, we cansay that probably there are significant differences between men andwomen buying in internet at Spanish homes.

The conversion from radians to degrees and vice versa can be see asa case of equivalent ratios or fractions; or as a case ofproportions.

There are six rounds, progressing in order from one to six, wherethe number of the round serves as the target for that round'srolls. Within a round, players alternate turns rolling three dice,aiming to obtain the target number. Players gain one point for eachdice matching the target. If the player gets three of a kind of thetarget number, he declares a Bunco and gets 21 points. The roundstops when a player obtains 21 points. Whoever wins the most roundsis the overall winner. This is a version with two players: you andyour device.

This application allows to practice multi-digits division using thestandard algorithm. The interface has been simplified as much ashas been possible. The application starts in an screen with adivisor of 1 digit and the instructions to make the proposeddivision. When you press the back button, the application shows thescreen with the simplest task and you can display a dropdown menuwith all the available options: "FORMING GROUPS THAT ARE EQUAL INSIZE" introduces you the concept of division. "DIVIDEND, DIVISORAND QUOTIENT" captures these three concepts with practice."REMAINDER" is another concept that emerges in the same way whenthe division of integer numbers is not exact. "WORK WITH DIVISOR OF2 DIGITS" allows practice the standard algorithm with this kind ofdivision. "WORK WITH DIVISOR OF 3 DIGITS" and "WORK WITH DIVISOR OF4 DIGITS" are similar to the previous one. "HOMEWORK" allows sendby email some divisions and its results with the number of digitsused last time. "SCORE TO ZERO" to reset the saved bookmark. Theapplication uses a lot of feedback by text and text to speech,allowing that students can follow easily the development ofarithmetic operations.

The Android application helps you to understand how to calculatethe Highest Common Divisor using the prime factor decomposition ofthe numbers.

Acute, right, obtuse, straight,complementary,supplementary and congruent angles

App generates simple random numbers to be decomposed into theirprime factors. You can go on step by step, beginning from thelowest factor to the highest one. You can enter your number to befactored.

The GRAPHICS option shows the sine, cosine and tangent of an anglein a circle of radius equal to one. You can use this graphic as aninteractive trigonometric tables by touching on the circle or byentering the angle value in degrees. The RIGHT TRIANGLE optiondescribes how to calculate sine and cosine in a right triangle andasks you to estimate some values. The option GRAPHING FUNCTIONSaccesses the representation of the trigonometric functions onCartesian coordinate axes (abscissa and ordinate axes). You canselect the function that you want to represent (sine, cosine andtangent), modify its amplitude, period or midline, obtaining itsrepresentation and the display of the corresponding function (forexample: f (x) = 1 + 3 sine 2x ). It also has several HELPS andvisualization of the most relevant IDENTITIES of trigonometricfunctions.

Your blued tank is in a maze with lot ofenemyred tanksYou can program games for various platforms with what youlearnto do from a MOOC.This game has been made during the course "Introduction togamedevelopment with Unity3D" (mooc.uji.es) to which have beenaddedknowledge of standard animations, coroutines, maintenanceofapplication variables and interfaces for mobile devices taughtinthe "UNY201.x of UPValenciaX" course. The final of the lastcoursewas overlapped with the first weeks of the course organizedby theUniversitat Jaume I.

AREA You can get the area and plane of a polygon following each ofits vertices and getting its positions with the GPS of a mobiledevice. The application displays an estimation of absolute errorand the relative error in the measurements. Because GPS positionshave an error, the application is not useful for measuring smallareas. The app is helpful for the estimation of: - The areas ofland in agricultural or forest crops. - Land areas when there arenot sight lines between vertices (You cannot use telemeters). -Water areas on the sea. In other cases, you should seriouslyconsider the relative error in the measurements. Interfaceimproved: saved positions with feedback to user when there is aninternet connexion.
