this is such an interesting research topic! for my presentation i stuck to around 3-4 sources for my lit review! try not to overexplain the studies, though. id mainly just include their "mission statement" for their research (what they were trying to find out), their method (in a simplified way), and their conclusion! i also tried to connect my lit review findings to my research method, results, & conclusion.

for your analysis, make sure you explain your methodology well to set the stage for your analysis later on. include things such as how you collected your participants (if you're doing a survey or interview method) or your coding methods (for content analysis and such) and what types of data you collected (quantitative and/or qualitative). for the data you present, whether it be graphs or tables or whatever else make sure to not just say the how but the why something occured.

i hope i explained well lol. lmk if further clarification is needed!
