If by positive you mean that an increase in the independent variable is accompanied by an increase in the dependent variable then this will be indicated by a correlation close to one.
What is considered 'close to one' depends on the field of study. In some fields where it can be quite difficult to establish relationships between variables a correlation of, say, 0.35 might be considered important, provided of course that it has been shown to be statistically significant.

What is a positive linear relationship?
A linear relationship is one where your equation forms a straight line. A positive linear relationship is one where this line has a positive gradient.
What does a scatter plot with strong positive correlation look like?
The line that connects the dots is relatively straight.
What is it called When a line graphs data points do not fall along a straight line?
When the data points on a line graph do not fall along a straight line, it is referred to as a nonlinear relationship. This indicates that the relationship between the variables is more complex, potentially involving curves or other shapes rather than a simple linear correlation. Nonlinear patterns can arise from various factors, such as exponential growth, quadratic relationships, or cyclical trends.
What does a scatter plot look like Having a positive linear correlation?
It looks like a straight line increasing as the x-values increase. So basically a line that goes from the bottom left area to the top right area on a graph.
What is Definition of linear regression and correlation in statistics?
Whenever you are given a series of data points, you make a linear regression by estimating a line that comes as close to running through the points as possible. To maximize the accuracy of this line, it is constructed as a Least Square Regression Line (LSRL for short). The regression is the difference between the actual y value of a data point and the y value predicted by your line, and the LSRL minimizes the sum of all the squares of your regression on the line. A Correlation is a number between -1 and 1 that indicates how well a straight line represents a series of points. A value greater than one means it shows a positive slope; a value less than one, a negative slope. The farther away the correlation is from 0, the less accurately a straight line describes the data.
What are Four Different Types of Correlations?
The four different types of correlations are positive, negative, zero, and nonlinear correlations. In a positive correlation, as one variable increases, the other also increases. In a negative correlation, as one variable increases, the other decreases. A zero correlation indicates no relationship between the variables, while a nonlinear correlation shows a relationship that does not follow a straight line, meaning the association changes in strength or direction at different levels of the variables.
What graph best shows correlation?
A scatter plot is the best graph to show correlation between two variables. In a scatter plot, individual data points are plotted on a Cartesian plane, allowing for a visual representation of the relationship between the variables. If the points tend to cluster along a line, it indicates a strong correlation, whether positive or negative. The closer the points are to forming a straight line, the stronger the correlation.
What you mean by linear relationship?
A linear relationship refers to a direct proportional connection between two variables, where a change in one variable results in a consistent change in the other. This relationship can be represented graphically as a straight line on a coordinate plane, typically described by the equation (y = mx + b), where (m) is the slope and (b) is the y-intercept. In this context, the slope indicates the rate of change between the variables, and a positive slope reflects a direct correlation, while a negative slope indicates an inverse correlation.
Does a correlation close to -1 or 1 always guarantee a linear relationship?
A correlation close to -1 or 1 indicates a strong linear relationship between two variables, but it does not guarantee that the relationship is strictly linear. Correlation measures the strength and direction of a linear association, and while a high correlation suggests that the points tend to align closely along a straight line, it can still be influenced by non-linear relationships or outliers. Therefore, it's essential to visually inspect the data and consider other analyses to confirm the nature of the relationship.
The straight line on the graph tells us about the relationship between two temperatures?
A line on a graph that compares two variables, temperature for example tells us a great deal about the relationship of these variables in the experimental system. When the line is straight it reflects a direct and proportional relationship between the two factors.
What is a positive linear relationship?
A linear relationship is one where your equation forms a straight line. A positive linear relationship is one where this line has a positive gradient.
What does a scatter plot with strong positive correlation look like?
The line that connects the dots is relatively straight.
What does a straight line on a graph means there is a relationship between the dependent variable and the independent variable?
A straight line on a graph indicates a linear relationship between the dependent variable and the independent variable. This means that as the independent variable changes, the dependent variable changes at a constant rate. The slope of the line represents this rate of change, while the y-intercept indicates the value of the dependent variable when the independent variable is zero. Overall, a straight line signifies predictability and a consistent correlation between the two variables.
If a graph of distance versus time is a straight line the graph shows what relationship?
it is a positive relationship
When a man cheats in the beginning of a new relationship?
This usually indicates he will never be committed to your relationship. It is better to end the new relationship with him straight away.
What graph indicates that there is a linear relationship?
A straight line graph plotted on the Cartesian plane
The relationship where 2 variables move in the same direction are called what?
A direct correlation, it appears as a straight line on a graph and occurs when variables are related as y=xk.
