Why would you use the mean and standard deviation for interval data? And when would you use the mode?

For the design part, do I have to mention single blind or double blind as well?

how long should we spend on the design of a study question because I am doing a question and it's nearly taking me 40mins to complete - I spent 5mins planning (it is a 10 marker, which says I need to operationalise the IV and DV and say how I should control the extraneous variables and says I should make the procedures and add sufficient detail so it can be carried out)? Also, when the question does not refer to the 'justify your choices' statement (this was the circumstance for the question I referred), do you justify them or not because how will you be able to get marks?

Do you think it’ll be a design a study this year or a different kind of question like consent/debrief form ?
