If you're curious about the mathematical ins and outs of probability, you've come to the right unit! Here, we'll take a deep dive into the many ways we can calculate the likelihood of different outcomes.
Learn a powerful collection of methods for working with data! AP®️ Statistics is all about collecting, displaying, summarizing, interpreting, and making inferences from data.
The bias of an estimator is the difference between this estimator's expected value and the true value of the parameter being estimated. An estimator or decision rule with zero bias is called unbiased. In statistics, "bias" is an objective property of an estimator. Does this help?
29 wrz 2020 · Sal shows how outliers and high-leverage points can be influential to different measurements like the slope, y-intercept, and correlation coefficient (r) in least-squares regression. View more ...
What’s the probability of the coin landing on Heads? We can find out using the equation P ( H ) = ? .You might intuitively know that the likelihood is half/half, or 50%. But how do we work that out?
Calculate: Perform mathematical steps to arrive at a final answer (e.g., algebraic expressions or diagrams with properly substituted numbers and correct labeling).
It is defined as the radius of a circle, centered on the aimpoint, that is expected to enclose the landing points of 50% of the rounds; said otherwise, it is the median error radius.
