Advanced Placement (AP) Statistics (also known as AP Stats) is a college-level high school statistics course offered in the United States through the College Board's Advanced Placement program. This course is equivalent to a one semester, non- calculus -based introductory college statistics course and is normally offered to sophomores , juniors ...
Spaced repetition is an evidence-based learning technique that is usually performed with flashcards. Newly introduced and more difficult flashcards are shown more frequently, while older and less difficult flashcards are shown less frequently in order to exploit the psychological spacing effect. The use of spaced repetition has been proven to ...
In modern terms, he rejected the null hypothesis of equally likely male and female births at the p = 1/2 82 significance level. Laplace considered the statistics of almost half a million births. The statistics showed an excess of boys compared to girls. [5] He concluded by calculation of a p-value that the excess was a real, but unexplained ...
The intercept is 2 and the slope is 4. Compare the result from the linear regression to the result from the t-test. From the t-test, the difference between the group means is 6-2=4. From the regression, the slope is also 4 indicating that a 1-unit change in drug dose (from 0 to 1) gives a 4-unit change in mean word recall (from 2 to 6).

In statistics, an empirical distribution function (a.k.a. an empirical cumulative distribution function, eCDF) is the distribution function associated with the empirical measure of a sample. [1] This cumulative distribution function is a step function that jumps up by 1/n at each of the n data points. Its value at any specified value of the ...
Independence is a fundamental notion in probability theory, as in statistics and the theory of stochastic processes.Two events are independent, statistically independent, or stochastically independent [1] if, informally speaking, the occurrence of one does not affect the probability of occurrence of the other or, equivalently, does not affect the odds.
The following techniques of distribution fitting exist: [2] Parametric methods, by which the parameters of the distribution are calculated from the data series. [3] The parametric methods are: Method of moments; Maximum spacing estimation; Method of L-moments [4] Maximum likelihood method [5]
