This video shows the process for solving the problem presented in IGCSE A June 2018 paper 2H Q7, which involves finding the mean and range. Students will understand the concept of mean and range in statistics and how to calculate them....

Learning about the anatomy of the brachial plexus can be tough. But, it can be quite easy if you have the right pneumonics to guide you. Watch this video as Leslie Samuel makes it fun and easier to go through each of the roots, trunks,...

👉 Learn how to find the mean, the median, and the mode of a set of data. The (arithmetic) mean of a set of data is the average of the set of data and is obtained by adding up the numbers in the set of data and dividing it by the count of...

👉 Learn how to solve with the ratio of sides and angles of a triangle. Given the ratio of the sides of a triangle and the perimeter of the triangle, we can solve for the actual lengths of the triangle. Similarly, when the ratio of the...

This video explains how to calculate different types of averages from a frequency table, such as mean, median, mode, and range. The instructor demonstrates step-by-step how to create the fx column to find the total amount of data, and...

👉 Learn how to solve proportions. Two ratios are said to be proportional when the two ratios are equal. Thus, proportion problems are problems involving the equality of two ratios. When given a proportion problem with an unknown, we...

In this video, the teacher explains how to compare the variability in weights of professional baseball and soccer players using medians and interquartile ranges. They demonstrate that while baseball players are heavier on average, soccer...

👉 Learn how to solve with similar triangles. Two triangles are said to be similar if the corresponding angles are congruent (equal). Note that two triangles are similar does not imply that the length of the sides are equal but the sides...

This video explains the different measures of variation, specifically the range, interquartile range, and percentile range. The host demonstrates how each measure is calculated and defines the various quartiles and percentiles used in...

In this video, students are taught to read and interpret dot and line plots, and use them to estimate the median of each population. By comparing the medians, students can make inferences about the data and draw conclusions about which...

In this video, students will learn how to describe the spread of data using different measures. They will be introduced to the concepts of range, interquartile range, and mean absolute deviation.

👉 Learn how to find the mean, the median, and the mode of a set of data. The (arithmetic) mean of a set of data is the average of the set of data and is obtained by adding up the numbers in the set of data and dividing it by the count of...

👉 Learn about dilations. Dilation is the transformation of a shape by a scale factor to produce an image that is similar to the original shape but is different in size from the original shape. A dilation that creates a larger image is...

This video explains how to calculate averages (mean, median, mode, and range) from a grouped frequency table. The presenter demonstrates how to estimate the mean using midpoints and frequencies, how to calculate the median using the...

SchoolOnline's Secondary Maths videos are brilliant, bite-size tutorial videos delivered by examiners. Ideal for ages 13-17, they cover every key topic and sub topic covered in GCSE Maths in clear and easy to follow...

This video explains what box plots are and how to interpret and construct them. It provides specific information on the different components of a box plot, including the minimum and maximum values, quartiles, range, and median. The video...

👉 Learn how to solve with similar triangles. Two triangles are said to be similar if the corresponding angles are congruent (equal). Note that two triangles are similar does not imply that the length of the sides are equal but the sides...

This video explains the concept of quartiles and box plots, which are used to analyze and visualize data sets. The video also explains how to determine the quartiles using a cumulative frequency graph and how to draw a box plot to...

In this video, students learn how to represent outliers in a boxplot by using quartiles. The video explains the five-number summary of a boxplot and demonstrates how to calculate the interquartile range. It then shows how to identify and...

This video is a musical tribute to William McKinley, the 25th President of the United States, who is remembered for his love of the gold standard and his role in the Spanish-American War, which unknowingly sparked the beginning of US...

In this video, students learn about the difference between the measure of center and the measure of variance. They use a line plot and a number line to find the median and variance of a set of data. The teacher explains that the measure...

Explore the concepts of median, mode, and range, and demonstrates how these measures can help determine which graph would be most useful. This video provides examples and comparisons of dot plots, histograms, and box plots, highlighting...
