The normal distribution is a bell-shaped curve where data clusters symmetrically around the mean, useful in statistics and natural phenomena modeling.
In simple terms, statistical significance is a measure of whether an observed effect or relationship in your data is likely to be genuine or if it could have occurred by chance. It provides a level of confidence that the results you see are not random anomalies but are reflective of a real...

A confidence interval, in statistics, refers to the probability that apopulationparameter will fall between a set of values for a certain proportion of times. Analysts often use confidence intervals that contain either 95% or 99% of expected observations. Thus, if a point estimate is generated ...
The p-value hypothesis test does not necessarily make use of a preselected confidence level at which the investor should reset the null hypothesis that the returns are equivalent. Instead, it provides a measure of how much evidence there is to reject the null hypothesis. The smaller the p-valu...
said hypothesis is assumed, for the sake of argument, to be true. Then the likely range of possible values of the calculated statistic (e.g., the average score on 30 students’ tests) is determined under this presumption (e.g., the range of plausible averages might range from 6.2 to ...
