In Australia the government requires the testing of students in Years 3, 5, 7 and 9 annually. They are tested on several aspects of English and Mathematics each year in order to assess their strengths and weaknesses in reading, writing, language conventions - such as spelling, grammar, and punctuation - and numeracy. “NAPLAN” stands for National Assessment Program - Literacy and Numeracy. All students take the same test for their individual year level, and each stage/year gets progressively more difficult as they go through their education. This data is used to assess how well they are doing compared to expected levels, and to calculate the national and state averages in each of the aspects.
I have chosen two variables that are individually described as the explanatory (or predictor) variable and response (or outcome) variable. A variable that can be used to explain, or can be said to cause differences in another variable is called an explanatory variable. The variable in which the differences are observed is called the response variable.
I am interested in the relationship between writing (describe) and the spelling. Because of these choices, my response (outcome) variable will be the demonstrated proficiency to spell …show more content…
We can see that for a small interval of around 50 points that writing proficiency increases, the proficiency in spelling seems to increase by around the same amount. From this we can see the positive associated demonstrated, though not very clearly.
This graph appears to have a linear trend, and does not seem to have a particularly strong relationship between the two variables, perhaps it could be considered moderate at this stage. The trend is not clear, as there is a lot of
