This video deals with the exciting topic of data! This is the first video in a series dealing with Statistics and Probability. Looking at exciting things like data and variables and the different types thereof. Numerical and Categorical Data. Discrete and Continuous data. What is a population? What is a sample? What is an observation? And so much more.
This video is awesome and looks at how we can manipulate data to find the mean, median, mode and range. These are otherwise known as measures of central tendency or summary statistics! I look at a number of questions and how we can find the mean, median, mode and range for each. I look at what it means to find the mean, median, mode and range and what happens when we change the numbers in a list. Such fun!
So you want to know everything there is to know about dot plots and column graphs - well here is the video for you. I take a look at what dot plots are, and how they can be used to find the mode of data. I move onto looking at column graphs and how they can also be used to represent data before moving on to look at how we can use numerical graphs to find things like mean, median, mode, and range. There are some examples, and the video ends by looking at the tricks which can be used in Mathematics to try and confuse you. Not fair Barry!
This video will answer all your questions about line graphs. If you're in Year 7 or 8 and studying this topic, I show you what we use line graphs for. I talk about continuous data. I look at why we do dots and lines. I look at what we name the axes and, most importantly, how to draw line graphs from some awesome questions. The last part of the video looks at distance-time graphs and we look at how the gradient of the lines means speed.
This is the most exciting video on stem and leaf plots. If you don't know how to draw them, I'll show you. If you don't know what they are ... I'll show you. If you don't know how to read them ... I'll show you. They are an awesome way to show numerical data without losing the actual data. They can be used to find the mean, median, mode and range. They are, in short, pretty awesome.
This video will let you know everything you could ever want to know about pie charts and divided bar graphs. Do you want to know how to draw a pie chart? This is the video. Do you want to know how to draw a divided bar graph? This is the video? Do you want to know how to measure and draw angles in pie charts? This is the video for you? Are you interested in knowing how to read a pie chart and talk about what it shows!? This is the video for you. Examples, humour and more in this awesome video for you.
Using words like unlikely, certain, impossible, possible, very likely etc to describe the chance of getting something.
This video looks at Theoretical probability by looking at possible outcomes, sample spaces and then how we use short hand notation to be able to make life easier for ourselves. Some examples of finding probabilities lead into a quick discussion of finding the complement of a probability.
This video will introduce you to the the ideas behind experimental probability by recapping a previous video on Theoretical Probability. And exciting stuff it is too! We do experiments to prove whether things are right or wrong. And this is also true in Mathematics.
