In this chapter, I learnt how to understand the correlation of a line on a graph. I also learnt how to calculate for values such as a(y-intercept) and b(slope). I learnt about residuals and regression and how to use variation when solving problems

In this chapter, I learned about inferences on 2 different samples. Through understanding the hypothesis table, and through t and z tests too. As well as how to solve when it asks about 2 independent samples.

In this chapter , I learnt how and why we must do hypothsis testing. I learnt the 6 major steps that are crucial for identifying hypothesis, and identifying if there is enough evidence to hold or reject.

In this chapter, I learned about 2 major topics. Standard Deviation & Mean. Not to mention range, median and mode. Understanding How to solve and find the Variance, is important for most problems professionals must deal with.

Couple in Test 1 Review.
1. Find the Mean.
2. Calculate the median
3. Suppose we added California, with $62.1 million in funding, to the data set. Recompute the mean and the median. Which is more affected by the presence of California? What can we say about each of the mean and the median, with respect to extreme values?

There is a lot I have learnt after watching the H5P Notes, one of which that I have enjoyed learning about was how statistics isn't just a number that denotes a population or a sample. But rather denotes a percentage of a study that one is intrested in.
