What kind of garph is most useful for showing the relationship between two numerical variables?
A line graph is the most useful type of graph for showing the relationship between two numerical variables. A bar graph can also be used since these two types of graphs are straightforward and simple.
What is the Advantages of scatter diagram?
It allows a quick look at the data to establish whether or not there is any relationship between the variables and also an indication of the nature of the relationship: linear, quadratic, power etc.
What does no trend mean?
Usually the expression is employed in the context of the relationship between a dependent variable and another variable. The latter may or may not be independent: often it is time but that is not necessary. In some cases there is some indication that that there is a linear relationship between the two variables and that relationship is referred to as a trend.Note that a trend is not the same as causation. There may appear to be a strong linear trend between two variables but the variables may not be directly related at all: they may both be related to a third variable. Also, the absence of linear trends does not imply that the variables are unrelated: there may be non-linear relationships.
What does correlation coefficient of 0.15 indicates which type of relationship between variable?
A correlation coefficient of 0.15 indicates a weak positive relationship between the two variables. This means that as one variable increases, there is a slight tendency for the other variable to also increase, but the relationship is not strong or consistent. It suggests that other factors may be influencing the variables, and the correlation is not significant enough to imply a definitive link.
State the function and purpose of scatter diagram?
To give a quick visual impression of the relationship between two variables. Also to allow outliers to be spotted easily.
What kind of relationship exists between the variables if your r value is close to plus 1?
When r is close to +1 the variables have a positive correlation between them; as the x-values increase, the corresponding y-values increase. There is also a strong linear correlation or relationship between the variables, when the value of r is close to +1.
What is the casual-comparative research method?
Casual-comparative research method is a type of research design that involves examining the relationship between variables without manipulating them. It aims to determine if there is a cause-and-effect relationship between the variables being studied. This method is also known as quasi-experimental research.
What is the relationship between the variables p and x in the given equation?
In the given equation, the variables p and x have a direct relationship. This means that as the value of p increases, the value of x also increases, and vice versa.
What is the relationship between the variables represented in the chart titled "X vs Y"?
The relationship between the variables represented in the chart titled "X vs Y" shows a positive correlation, indicating that as variable X increases, variable Y also increases.
What is the relationship between the variables represented in the graph titled "X vs Y"?
The relationship between the variables represented in the graph titled "X vs Y" shows a positive correlation, meaning as the value of X increases, the value of Y also increases.
What is the difference between a manipulated and responding variable?
Manipulated variables are also known as independent variables. These are the variable which you change in an investigation. Plotted on the x axis.
What kind of garph is most useful for showing the relationship between two numerical variables?
A line graph is the most useful type of graph for showing the relationship between two numerical variables. A bar graph can also be used since these two types of graphs are straightforward and simple.
What is the relationship between temperature and frequency?
The relationship between temperature and frequency is that as temperature increases, the frequency of a wave also increases. This is known as the temperature-frequency relationship.
What does the power vs force graph reveal about the relationship between the two variables?
The power vs force graph shows that as power increases, force also tends to increase. This indicates a positive relationship between the two variables, where higher levels of power are associated with higher levels of force.
What does ''highly correlated'' mean?
Correlation is defined as the degree of relationship between two or more variables. It is also called the simple correlation. The degree of relationship between two or more variables is called multi correlation. when two or more variables are said to be higjly correlated it means that they have a strong relationship such that a given rise or fall in one variable will lead to a direct change in the other variable or variables. good examples of highly correlated variables are price and quantity, wage rate and out put, tax and income.
What 2 things does a formula tell you?
A formula tells you the relationship between different variables and how they interact with each other. It also helps you calculate or predict specific outcomes based on the given variables.
What is the Advantages of scatter diagram?
It allows a quick look at the data to establish whether or not there is any relationship between the variables and also an indication of the nature of the relationship: linear, quadratic, power etc.
