# Estimate Probabilities from Experimental Data

Students learn how to estimate probabilities from experimental data to check for bias.  As learning progresses they consider the effect of the sample size and relative frequency.

The start of the lesson recaps writing theoretical probabilities as fractions.  In the plenary, students are challenged to consider three sets of results with different sample sizes and decide which set of data is the most reliable.

##### Differentiated Learning Objectives
• All students should be able to estimate a probability from experimental data.
• Most students should be able to estimate a probability from experimental data and identify bias.
• Some students should be able to understand how sample size affects relative frequency.

#### Surface Area of Cylinders

When I teach how to find the surface area of cylinders I like to add a constant level of challenge and enjoyment to the lesson.  Rather than repetitively calculating the surface area of a cylinder I introduce more complex cylindrical shapes.

#### Teaching Mathematics for a Growth Mindset

Inspiring students to enjoy maths and feel the success that comes with attempting a difficult challenge is why I teach.  The feeling of success is addictive.  The more students experience it the more they want it and the further out of their comfort zone they are willing to go to get more of it.  Teaching […]

#### Equation of Straight Line Graphs

To find the equation of straight line graphs students need to calculate the gradient using two pairs of coordinates and the intercept which is the y value of where it crosses the vertical axis.  Examiner’s reports of past exam questions show students are more able to find the intercept of a straight line than they […]
