This video forms part of the General Mathematics Units 1 and 2 course and deals with the Statistics and Data section. I know you've been lying awake at night worried about all the different types of data there are! So, I've recorded a video to allow you to sleep easy at night. Watch the video and you'll know what data is. You'll understand what categorical and numerical data is. You'll even understand the difference between ordinal, nominal, discrete and continuous data. All delivered in my usual easy to understand and entertaining way. Try me. Trust me. I've got your back!
This is the second video in the series dealing with Data and Statistics from the General Mathematics course. So, we've looked at data and now we're looking at frequency tables and how we can best represent them. You have already met them before ... but we now look at our trusted friend (the Bar Chart) in a whole new way. I take a look at how to represent data using a bar chart. I look at two different charts; frequency bar chart and percentage frequency bar chart. Using my own brand of teaching and entertainment I hope I can make the content seem easy to understand.
Another video in the General Maths series looking at Data and Statistics and I've loved recording this video. Building on the last video, I look at how we can interpret data to write a meaningful and concise report. Limiting the report to categorical data and either a frequency table or bar chart, I look at how to structure a report which will gain you the maximum of marks. Delivered in my own unique style with cutting edge humour and comments which seem to come from left field! I am trying to get everyone to understand Maths and realise it's all smoke and mirrors!
Another video in the General Mathematics Series, this one looking at Displaying and describing numerical data. Statistics and Data are really important in this course and later courses which you might study. I take a look at how to display numerical data using the wonderful thing called a Histrogram! I look at how we can graph discrete data as well as large data sets using the principal of intervals!!! So much fun and lots of examples make the theory clear and lead to you understanding and smashing those tests and exams. I deliver using my own unique style of teaching and hope you enjoy the lesson.
More videos looking at the Data and Statistics section of the General Mathematics course. Having looked at Histograms, I thought it was time to look at how you can describe the shape, location and spread of a histogram. Why? Well, it's going to become very important as time goes on! Particularly in later courses. I do a number of worked examples and show you what to look for when considering the shape, location and spread of data. All with my own brand of Maffsguru humour and teaching!
This is another video in the General Math series looking at Data and Statistics. What a joy to behold! Not me ... Dot plots and Stem and Leaf plots. This video will show you the hidden treasures which are Dot plots and Stem and Leaf plots. I look at how to construct them and what they are used for. This is more of an introduction to help with later videos where we will analyse the data and write some pretty funky reports on. There are worked examples all delivered with my own unique style of humour!
This is another video in the General Maths Units 1 and 2 course. This one looks at how we can use summary statistics to summarise data. I take a look the how to find the mean (and what that actually means). We look at finding the median for both odd and even numbers of data items. The range follows with a discussion about how this isn't a great measure of anything. I look at a comparison between the median and the mean and which is the best to use before heading into the excitement which is the Interquartile range. Finally I look at what the standard deviation is and how we find it using pencil and paper and CAS. There are a number of worked examples and all the theory is explained in my own unique style!
This is another video for the Year 11 General Maths series looking at boxplots. I take some time to look at how we can get the data from the CAS to draw a box plot, how to draw a boxplot and how to calculate and show the outliers for a box plot. There are a number of examples shown which clearly explain how to draw a boxplot like a Boss! All explained with my own unique teaching style. You'll never make another mistake with a boxplot again.
This is another video is the General Maths series for Year 11 dealing with comparing the distribution of a numerical variable across two or more. Statistics is about comparing data. We can use stem plots and parallel box plots to help us describe the trends in categorical and numerical data. Shape, centre, spread and outliers are all things which these wonderful diagrams can help us identify and compare. I use a number of worked examples to explain how to get the most marks in a statistical investigation. All delivered in my own unique style!
