AOA, I learned in this lecture about descriptive statistics that we need to know what a sample is and what a population is, as well as what the central tendency (mean, median, mode) is, what is spread, and what the outliers are. Different data visualization tools should also be known. and also learned about the t-test (sample 30), as well as the different kinds of the t-test (one sample, unpaired, paired).ALLAH PAK ap ko dono jahan ki bhalian aata kry AAMEEN.
