This series of interactive excel sheets explore the product moment correlation coefficient (PMCC). Another title can be found in our Virtual Textbook: Secondary collection.

...

This series of interactive excel sheets look at projectiles, either on or above the horizontal plane.

The first sheet defines the symbols and units used the remaining sheets.

...

This interactive workbook begins with a sheet which illustrate properties of odd, even and consecutive numbers. These properties are illustrated numerically and algebraically. The next two sheets deal with properties of the sum, difference and product of these numbers...

This interactive resource, produced by the University of Leicester, is designed to enable students to explore what is meant by a quadratic equation, the meaning of the coefficients of a quadratic equation and to be able to solve quadratic equations. An introduction page gives examples of where quadratic equations...

This resource contains four excel programs with interactive spreadsheets dealing with topics relating to quadratic expressions, their graphs and solving quadratic equations.

...

This collection of interactive excel sheets look at radians, arc length, sector area, converting to and from degrees, and other related problems.

The first sheet displays a sector of a circle and corresponding...

This interactive file shows the graphs of functions and the graph of the corresponding reciprocal function. It begins with the graph of a linear function where the gradient and intercept can be changed. The reciprocal is plotted on the same diagram. The next two sheets...

This is a series of interactive excel sheets exploring linear regression.

The first sheet plots a scatter diagram and line of best fit for a small set of bivariate data. The mean and product moment correlation...

This engineering resource, produced by Mathematics in Education and Industry (MEI) for the Royal Academy of Engineering, asks the question: how can production outcome data from a manufacturing process be analysed to optimise the process? Students consider the outputs of resistors to see the outcomes form a normal...

This file illustrates the use of the Sigma notation particularly with linear expressions. It begins with a static sheet showing four examples including some non-linear examples suitable for class discussion.

The...

This contains two excel programs with interactive spreadsheets designed to show the graphical solution to pairs of simultaneous equations and provide their solutions.

...

This file provides practice at solving pairs of simultaneous equations where at least one is not linear. The pairs of graphs and the coordinates of the points of intersection can be revealed.

The first sheet deals...

This is a series of interactive excel sheets that explore the different methods for calculating standard deviation.

The first sheet helps demonstrate the method for finding the standard deviation from population data...

This series of interactive excel sheets look systems in static equilibrium.

The first sheet looks at two forces acting on a point. A new question can be generated by clicking “new diagram” in which the angle and value...
