Learn Zillion: Predict the Frequency of an Event Using Results From Experiments

Emerging statisticians develop the ability to make inferences from sample data while also working on proportional relationships in general. Here, young learners examine samples for bias, and then use random samples to make...

Frequency polygons are a different way to represent frequencies over intervals. Pupils take frequencies for intervals of data from a frequency table and plot them as a frequency polygon. Budding mathematicians find information about the...

Pupils use the provided census data to guess the future height of a child. They organize and plot the data, solve for the line of best fit, and determine the likely height and range for a specific age. 

Class members are introduced to probability using terms such as impossible, unlikely, likely, and certain. Numbers between zero and one are associated with the descriptions of probability. Pupils find the likelihood of chance experiments...

You have a greater chance of being crushed by a vending machine than winning the Powerball lottery. Part of The Lowdown: Real-World Math series, an engaging video describes how the Powerball works and how to calculate the probability of...

Your learners will be surprised by the thought-provoking, counterintuitive puzzle presented in this short video that models a fun, fictional situation in which a game is played with two number cubes to decide which of two people wins a...

Creating a cumulative frequency graph is one thing, reading them is another. A thorough video lesson explains how to find key information from a cumulative frequency graph. The instructor demonstrates the best way to read the graph and...

Shorten the calculations with the power of multiplication. Using the meaning of multiplication, the video shows a more efficient method of calculating the mean for data displayed in a frequency table. There is no need to write out each...

How many ways can you think of to display data? A quick video lesson describes the process of creating one of them, a line graph, which is also referred to as a frequency polygon. After creating the graph, the instructor models how to...

If you want more pumpkin seeds, you should get a bigger pumpkin—right? Young harvesters use estimation skills to make a hypothesis about how many seeds they will find in a pumpkin before examining the real number inside.
