1/15뒤로Skip to main content뒤로Correlation Coefficient
A numerical measure indicating the strength and direction of a linear relationship between two variables in a dataset. Population Correlation Coefficient
A parameter representing the true linear relationship between two variables across an entire population. Sample Correlation Coefficient
A statistic calculated from sample data to estimate the strength and direction of a linear relationship. Null Hypothesis
A statement asserting no linear correlation exists between two variables, often represented by a population parameter equal to zero. Alternative Hypothesis
A claim suggesting a linear correlation exists between two variables, differing from the null hypothesis. Degrees of Freedom
A value calculated as sample size minus two, used in statistical tests for correlation significance. Test Statistic
A calculated value used to assess the evidence against the null hypothesis in hypothesis testing. T Score
A value derived from the sample correlation coefficient and degrees of freedom, used to determine statistical significance. P Value
A probability indicating the likelihood of observing the sample data if the null hypothesis is true. Alpha
A threshold probability used to decide whether to reject the null hypothesis, commonly set at 0.05. Two-Tailed Test
A hypothesis test evaluating whether a parameter differs from a specified value in either direction. Linear Correlation
A relationship where changes in one variable are associated with proportional changes in another variable. Excel Function
A built-in formula used to compute statistical values such as correlation coefficients and p-values. R Squared
A value obtained by squaring the correlation coefficient, representing the proportion of variance explained. Significance
A determination that observed results are unlikely to have occurred by chance, based on statistical testing.
