What does a graph with no trend show about the variables?
that they will not be correct
When is there no trend line for a scatter plot?
When no possible relationship between the two variables in question is statistically significant.
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 it mean when something is directly proportional?
Directly proportional means that both variables increase or decrease at the same time.
Can variables be positive or negative?
both, variables can be anything
How is a line graph similar to a bar graph?
they're similar because the both of them trend and trend means to increase or decrease
What is a trend that occurs when both sets of data items increase?
Specify what you mean by "trend". The correlation remains the same. Specify what you mean by "increase". Multiplying will result in a difference in variance, addition will not.
The periodic trend for electronegativity is similar to what other trend?
The trend for first ionization energy
What does a graph with no trend show about variables?
that they will not be correct
What does a graph with no trend show about the variables?
that they will not be correct
What does the slope of a trend line tell you about the relationship between two quantities?
If the slope of the trend line between variables X and Y is m, then an increase in value of 1 unit in X is associated with an increase of m units in the value of Y. The relationship is one of association, not of cause-and-effect.
How is the electronagativity trend related to the first ionization energy trend?
Electronegativity and first ionization energy both increase as you move up the periodic table
How is the electronegative trend relate to the first ionization energy trend?
Electronegativity and first ionization energy both increase going up the Periodic Table.
How the electronegativity trend related to the first ionization energy trend?
Electronegativity and first ionization energy both increase going up the Periodic Table.
When is there no trend line for a scatter plot?
When no possible relationship between the two variables in question is statistically significant.
What does trend mean you math terms?
A trend is a math term. It is on a line graph. It is a slope between two variables.
