well i did initially think that too! that is that it meant data sources rather than data collected, but after my teacher not budging on my claim I checked d charles sturt site n in the glossary it does say "11.1b (identify data sources)
determine the type of data that needs to be collected and explain the qualitative or quantitative analysis that will be required for this data to be useful" so now I'm just lost on what a different "type" of data would be, I was thinking like you could have weights, densities etc but in the soda prac theres only weighing anyway n in the marking criteria it says theres gotta b 2 types of data collected ????
thanks for ur help though!!
