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 does Correlation of plus 1.00 mean?
It mean that there is no correlation between the two variables. The variables are the same.
If coefficient of correlation r between two variables is zero does it mean that there is no relationship between the variables Justify your answer?
"If coefficient of correlation, "r" between two variables is zero, does it mean that there is no relationship between the variables? Justify your answer".
State max number of points lie on graph of linear equation in two variables to represent this statement?
There is no "this statement" associated with the question, but the maximum number of points which lie of the graph of a linear equation in two variables is infinite.
When do you use a scatterplot?
Scatter plots are used to investigate a possible correlation between two variables that are associated with the same “event.”

What is the general form of linear equation in two variable?
ax + by + c = 0 where x and y are the variables, a, b and c are numerical constants.
What does correlation mean in maths?
Correlation is a statistical measure of the linear association between two variables. It is important to remember that correlation does not mean causation and also that the absence of correlation does not mean the two variables are unrelated.
What does 2n-m mean?
It is a linear expression in two variables.
What does it mean when two variables have a positive correlation?
A positive correlation between two variables means that there is a direct correlation between the variables. As one variable increases, the other variable will also increase.
State max number of points lie on graph of linear equation in two variables to represent this statement?
There is no "this statement" associated with the question, but the maximum number of points which lie of the graph of a linear equation in two variables is infinite.
What are the two types of data in scientific method?
Qualitative (things you can describe, like categories: gender or sport, variables like sm, m, and lg, or attitudes: agree/disagree, etc) and quantitative: things you can measure and report in numbers (like mass or volume)
