Use the scatterplot of distance/time data for a dropped object to find the value of the rank correlation coefficient r. and the critical values corresponding to a 0.05 significance level used to test the null hypothesis of ps =0. Determine whether there is a correlation. 1000 S00
Correlation
Correlation defines a relationship between two independent variables. It tells the degree to which variables move in relation to each other. When two sets of data are related to each other, there is a correlation between them.
Linear Correlation
A correlation is used to determine the relationships between numerical and categorical variables. In other words, it is an indicator of how things are connected to one another. The correlation analysis is the study of how variables are related.
Regression Analysis
Regression analysis is a statistical method in which it estimates the relationship between a dependent variable and one or more independent variable. In simple terms dependent variable is called as outcome variable and independent variable is called as predictors. Regression analysis is one of the methods to find the trends in data. The independent variable used in Regression analysis is named Predictor variable. It offers data of an associated dependent variable regarding a particular outcome.
B. The critical values are ±___
C. Is there a
- Fail to reject the null hypothesis. There is sufficient evidence to support a claim of correlation between distance and time.
- Reject the null hypothesis. There is sufficient evidence to support a claim of correlation between distance and time.
- Reject the null hypothesis. There is insufficient evidence to support a claim of correlation between distance and time.
- Fail to reject the null hypothesis. There is insufficient evidence to support a claim of correlation between distance and time.
