We may not know it, but averages affect our lives every day. Designers and manufacturers use averages to make our houses, cars, shoes and airline seats safer and more comfortable(ish). But calculating averages is way more complicated...

Today we’re going to talk about measures of central tendency - those are the numbers that tend to hang out in the middle of our data: the mean, the median, and mode. All of these numbers can be called “averages” and they’re the numbers...

In this video, we will look at the impact of the data changes we make with underlying data in the measures of central tendency or dispersion.

In this lecture, we will elaborate more about the third and final measure of central tendency, the mode.

In this lesson, we will discuss the second important measure of central tendency, the median.

This brief introduction to the section outlines what you will be learning from this section, including the basics of statistics.

Pupil outcome: I can use my understanding of various data summaries to solve problems. Key learning points: - Stated conclusions should be critically evaluated to ensure validity. - Certain statistical summaries may be omitted in the...

Pupil outcome: I can understand what the mode is measuring, how it is measuring it and find the mode from data presented in a list. Key learning points: - The mode is a measure of central tendency. - The mode is the most frequently...

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 the different measures of central tendency and spread to compare two sets of data. Key learning points: - Statistical summaries of data can be used to make inferences about that data. - Two sets of statistical...

Pupil outcome: I can identify the limitations of each measure of central tendency and identify which should be used. Key learning points: - The mode is a useful measure of central tendency for certain data sets. - The median is a useful...

Pupil outcome: I can understand what the median is measuring, how it is measuring it and find the median from data presented in a list. Key learning points: - The median is a measure of central tendency. - The median is the middle (or...

Pupil outcome: I can understand what the range is measuring, how it is measuring it and calculate the range from data presented in a range of different ways. Key learning points: - The range is a measure of spread. - The range is...

Pupil outcome: I can use the different statistical representations to compare two sets of data. Key learning points: - Statistical summaries can be compared to graphical representations of data. - Statistical summaries can be used to...

Pupil outcome: I can choose appropriate statistical measures to explore a statistical problem. Key learning points: - The type of data may mean that certain statistical measures are not appropriate. - The nature of the data may mean that...

Pupil outcome: I can evaluate different statistical measures to draw conclusions about a data set. Key learning points: - A statistical summary involves the mean, median, mode and range. - Each summary gives us different insights into a...

Pupil outcome: I can calculate the mean, median, mode and range from a list of data. Key learning points: - The mean, median and mode are measures of central tendency. - The range is a measure of the spread of the data. - Calculating...

Pupil outcome: I can understand what the mean is measuring, how it is measuring it and calculate the mean from data presented in a list. Key learning points: - The mean can be seen as a redistribution of values such that everything is...

Pupil outcome: I can calculate the mean from data presented in a frequency table and different graphs. Key learning points: - The mean can be calculated from a line graph. - The mean can be calculated from an ungrouped frequency table. -...

Pupil outcome: I can calculate the median from data presented in a frequency table and different graphs. Key learning points: - The median can be calculated from a line graph. - The median can be calculated from an ungrouped frequency...

Pupil outcome: I can analyse geographical data and use my findings to create different types of conclusions. Key learning points: - Quantitative data can be analysed using the GRaDE framework and simple statistical tests. - Qualitative...

By the end of this learning object, the student will be able to: List Standard Deviants Teaching Systems4462

"Statistical Measures" explains mean, median, mode, mean absolute deviation, range, and interquartile range.

A video entitled "Best fit" which explains how to calculate measures of center and measures of variation and discusses how to determine the value that best represents a data set.
