Consider the scatter plot and trend line to the right. Should the trend line for the temperature be expected to continue in the same direction indefinitely? Explain. 100- 90- 80- 70- 60- 501. 40 oi234 5 67 Time (hours) O A. No. It should not be expected to continue in the same direction indefinitely. Trend lines cannot be used to make inferences beyond the data used to make it. O B. No. It should not be expected to continue in the same direction indefinitely. The outdoor temperature should be expected to increase more and more quickly over time. This means if more data were collected, the pattern in the scatter plot would start to curve up. OC. Yes. It should be expected to continue in the same direction indefinitely. The trend line models the given data well, so it can be expected to also model the situation well as x increases indefinitely. O D. Yes. It should be expected to continue in the same direction indefinitely. The data have a clear association, so the trend line should accurately model the situation for all values of x O E. No. It should not be expected to continue in the same direction indefinitely. The outdoor temperature should be expected to increase more and more slowly over time. This means if more data were collected, the pattern in the scatter plot would start to curve down. Click Cwor and thon
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.
