Unit 6: Statistics
Overview
In Year 7, you learnt different ways of presenting and performing meaningful calculations on one variable (univariate data). Now in Year 8, you will learn different ways of presenting and performing meaningful calculations on two variables (bivariate data). You will also learn about continuous data.

To do well on this assessment you will need to do the following things:
Understand primary, secondary, discrete and continuous data and be able to identify examples of each.
Collect and record data using tally charts, two-way tables.
Calculate (with and without a spreadsheet) an estimate the mean, mode, median and range from a frequency table.
Produce (with and without a spreadsheet) and interpret a scatter graph, line of best fit for a bivariate data set.
Produce (with and without a spreadsheet) and interpret a histogram and a frequency polygon for continuous data.

Make conclusions based on the correlation between two sets of data.
Write a statistical report based on a data set containing at least two variables and including comparisons of those variables.
End of Unit Review
To support your revision, take a look at the following tasks:
Skills based practice on Dr Frost Maths - click here to check how well you have understood the learning objectives of this unit. You are encouraged to watch the relevant video and practise any skill that you find challenging.
Practice assessment - this is particularly focused on ensuring you have understood i) the statement of inquiry, key and related concepts in relation to the unit, ii) the assessment objective/rubric, iii) key command terms required to understand the assessment and iv) ATL skills you have developed over the unit. Make a copy of and attempt the practice assessment below (answers are here):

Make a copy of the document below and follow the following steps for your reflection:
During the Unit
At the beginning of the unit, use the traffic light system to rate how confident you are of the learning objectives. This will help you identify what areas you need to focus on in your lessons and self-study.
Add to the "What key skills have I learnt in the unit?" box key takeaways from your lessons and self-study. You may want use this as notes at the end of each lesson.
Add to the "What key skills do I still need to work on?" box key things that you still need further practice. Make sure you include resources like videos from DrFrostMaths, CorbettMaths, MyiMaths and Eedi etc.
At the end of the unit and prior to the assessment, use the traffic light system to rate how confident you are of the learning objectives. This will help you identify what areas you need to work on for your assessment.
After the assessment
Use the second part of the document to reflect on your assessment:
Add to the "What went well?" box a reflection of the positives. Make sure this is a reflection on the mathematics, not your effort.
Add to the "What do I need to improve on?" box reflection additional things you need to do to address the gaps of knowledge shown in the assessment. Be specific about how you can address the problems. You should start with “I need to… ”
Copy and paste what you wrote in the two boxes onto your student portfolio as part of your reflection for your target.
Upload your reflection document onto your student portfolio as evidence for your reflection.
