Let’s go through the most common types of questions:ġ. There are a few different aspects of the data you could usually be asked to outline. These questions usually ask you to describe some aspect of given data or a graph. So if its about the increase from January 18 to February 18, the denominator will be the January value whereas if you’re calculating the increase from February 18 to January 19 the denominator will be the February value.

*** Your denominator when calculating and increase/decrease should always be the original value.

Â Turn this Fraction into a percentage: 1.6/29.9 –> 5.3%.

Â Express the difference in mass as a fraction over the first value: 1.6 / 29.9.To calculate the two percentage difference: Using the data from the table, calculate the percentage difference in mean bird mass for the hermit thrushes refueling at Site 1 compared to those refueling at Site 2įor copyright reasons I cant include the graph itself, so I’ll just give you the two mean bird mass values for the hermit thrushes at the two refueling sites: I’m going to assume that you’re quite good at subtracting and adding values, but percentage increase/decrease can muddle some students up so lets go through an example from a past exam paper: Usually, these questions ask the candidate (you) to subtract 2 values, add 2 values or determine the percentage difference. Question: State the highest lipid content achieved by any group in the graph above.Ĭalculation questions are also easy, as the math itself does not require complex arithmetic. The only important thing to remember is that you always need to include units. Typically, these questions ask you to do one of the following: The aim of these questions is for the IB to know that you are able to correctly read a graph and interpret its data. These are typically the easiest questions on the paper, because all you have to do is identify a value from the graph without doing any sort of interpretation or calculation (usually). It is tempting to include a description of the graph in your evaluation, but try to come up with new points if you can, they’re more likely to be on the mark schemes.ĭata Based Questions usually start with a straight forward “state” question. Often the questions first ask you to describe a graph, then evaluate it. Which means that you should avoid repeating yourself if you can. Therefore, don’t make them read through loads of text before you get to the main points, sadly there’s a chance they’ll never read them if they don’t think you know what you’re talking aboutĤ. Strongest points first! When you’re asked to describe/ compare and contrast/ evaluate data, the examiner is looking to quickly be able to give you your marks. When the question asks you to describe the graph above (3), there are 3 available marks, you should describe 3 different aspects of the graph.ģ. Give as many points as there are marks available. A good general tip is to make sure every sentence addresses 1 key point in the question.Ģ. The reason being that in order to gain marks you need the examiners to pick up on your points, which therefore needs to be as easy as possible. Imagine the examiner is 5 years old and doesn’t have time for anything.

We will break down how to answer the following types of questions that are unique to DBQs.ġ. In this blog post, we break down all the different types of questions that get asked in the Paper 2 Data-Based Questions, to give you a massive advantage over all the other candidates. The myth goes that there’s simply no way to get good at these questions. The IB Biology Data Based Questions make up 20% of the paper 2 marks available.īut, if you’re like most other IB students, you absolutely hate the IB Biology Data Based Questions.
