What else can I help you with?
How you would know what variables are positively linearly correlated?
After the data is collected and graphed, it will be in a line virtually straight. You can then form a relationship using the basic linear formula and see if it is close enough to be acceptable.
When is data negatively or positively skewed?
i) Since Mean<Median the distribution is negatively skewed ii) Since Mean>Median the distribution is positively skewed iii) Median>Mode the distribution is positively skewed iv) Median<Mode the distribution is negatively skewed
What is an example of two variables that would be positively correlated and two variables that could be negatively correlated?
False. Correlation coefficient as denoted by r, ranges from -1 to 1. Coefficient of determination, or r squared ranges from 0 to 1. I note that x,y data points that have a high negative correlation would plot with a negative trend or a negatively sloped line if a best fit regression line is determined. I note also that x,y data points with a high positive correlation would plot with a positive trend or positively sloped line if a best fit regression line is determined. The coefficient of determination for r = 0.9 and r= -0.9 would be 0.81.
What does it mean to say that years of experience in a profession and income are positively correlated?
This means that the more years of experience that a person has the higher his or her income is likely to be.
Can the distribution of the mean median and mode be equal if the are positively skewed or negatively skewed or symmetric?
Not necessarily.
What insights can be gained from analyzing the relationship between variables in the graphs of x vs y or y vs x?
Analyzing the relationship between variables in graphs of x vs y or y vs x can provide insights into the nature of their relationship. By examining the direction, shape, and strength of the relationship, one can determine if the variables are positively correlated, negatively correlated, or not correlated at all. This analysis can help identify patterns, trends, and potential causal relationships between the variables.
If the value of two variables decreases are they positively correlated?
Not necessarily. They must decrease together (the question does not say so). Also, the decreases may not be sufficient for the to be correlated. It is less likely that they are negatively correlated, but with the amount of information in the question that is about all that can be said.
