I think you want to say something like:
"In an effort to alleviate her guilt about the past, Suyuan tried to live vicariously through her daughter. Though this caused conflict between the two, Suyuan's love for [her daughter's name] was unconditional ."
Your ideas are good, these are just some suggestions to help you use more precise language.
I'd also add something to clarify how the body of your essay will address the thesis - will you discuss the ways in which Suyuan tried to live through her daughter or focus more on examples of her love for her?
So I'm just guessing but for the first one, that looks like a discrete variable, as they are finite measurements. A continuous variable would have something like a height measurement, which can be an infinite variable, this means that a continuous variable can look like: 23.44345623424..... and go on forever. However a discrete variable is exact, such as the amount of fast food eaten per week, which could be 2 or 5 or 1. For the measures of central tendency, that is calculations such as the mean, median and mode. If you're looking at more advanced stuff you could be facing standard deviations and other such calculations. In this case the mean, median and mode are all appropriate. To calculate these measures, just look that up on google, they're pretty simple. As for meanings: MEAN: is the overall average (so the average amount of fast food eaten per week) MEDIAN: is the middle value, so you must arrange your values in ascending order (0-8) and then find the middle number (literally the number in the middle) so to find that middle number exactly (helps for large amounts of numbers) add up the number of numbers and divide that answer by two. If you get something like 14.5, then either round up, or include both the upper and lower number. MODE: is the value that occurs the most. So in this case it would be 0 and 3, as they both occur 3 times each.
For the second question's weird "cumulative frequencies" it looks like all you need to state is how many times that result occured, check this out. Looks like you just need to plot a stem and leaf chart or something like that.
Good luck!
This should help, you in the right direction, now even though this is cyclohexylacetic acid vs acetic acid (below) the principle should still be the same, let me know what answer you have and I'll show you mine.
