Pupil outcome: I can interpret data from a wide variety of graphs. Key learning points: - Graphs of data allow geographers to understand trends and correlations. - Bivariate graphical data allows geographers to predict other values...

Pupil outcome: I can interpret a cumulative frequency graph. Key learning points: - A cumulative frequency has values read in the same way as a line graph - The median is the 50th percentile - The lower quartile is the 25th percentile -...

Pupil outcome: I can construct a box plot. Key learning points: - A box plot requires 5 pieces of information - These are lowest value, lower quartile, median, upper quartile and highest value - Outliers should be included in the range...

Pupil outcome: I can calculate the IQR and interpret what this means. Key learning points: - The interquartile range tells us how spread out the middle 50% of the data is - This can be seen visually with a box plot - Box plots and...

Pupil outcome: I can use my knowledge of cumulative frequency and histograms to solve problems. Key learning points: - Different representations of the same data set give a fuller picture - It is important to identify what features are...

Pupil outcome: I can interpret a box plot and compare two box plots. Key learning points: - A box plot allows us to make conclusions about the data set - Box plots can be compared to highlight similarities/differences in data sets - The...

In this math video we will be identifying measures of spread. We will understand that our statistical measures of data are mean, median, mode, range and IQR (interquartile range). We will learn that there are two categories of measure -...

In this video, we will learn how to create and interpret box and whisker plots. Box and whisker plots are a type of graph that can be used to display the distribution of data. They are made up of a box, whiskers, and a median. The...

Create a Box Plot creates a box plot by using given data.

The aim of this video is to explore statistical functions for inference.

It explains the limitations of measures of central tendency and hence the need of measures of dispersion. It also introduces various measures of dispersion.

This video is a tutorial on quartiles and interquartile range. The speaker explains the concept of quartiles and their usefulness in analyzing data distribution. The video discusses how quartiles can be used to identify specific points...

Using examples of different research studies, this video demonstrates how to interpret the data in the box plots to make informed decisions about the effectiveness of different treatments. This lesson provides a clear and concise...

Find the minimum, maximum, quartiles, and Interquartile range for a data set.

Create box plots.

This video shows the process for solving the problem presented in IGCSE A June 2018 paper 2HR Q11, which involves cumulative frequency tables. Students will understand how to interpret a frequency table, the concept of a cumulative...

This video explains how to collect data from a cumulative frequency graph and how to use that data to find an estimate for the interquartile range. Source of question: IGCSE A June 2018 paper 1H Q10.

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...
