The statement about the correlation between the number of hours a person studies and their exam score is true; generally, more study hours lead to higher scores, indicating a positive correlation. Similarly, there is often a positive correlation between a child's age and their height, as children typically grow taller as they get older. As for the speed of a vehicle, it would depend on the context; if you're referring to speed increasing with time or distance, that could also represent a positive correlation.

How do you calculate degrees of freedom for a correlation?
To calculate the degrees of freedom for a correlation, you have to subtract 2 from the total number of pairs of observations. If we denote degrees of freedom by df, and the total number of pairs of observations by N, then: Degrees of freedom, df=N-2. For instance, if you observed height and weight in 100 subjects, you have 100 pairs of observations since each observation of height and weight constitutes one pair. If you want to calcualte the correlation for these two variables (height and weight), your degrees of freedom would be calculated as follows: N=100 df=N-2 Therefore, df=100-2=98 The degrees of freedom are a function of the parameters; you subtract the amount of parameters free to vary from the n to get the df, so logically in a correlation we should subtract 2 from n, as we are looking at a correlation between 2 variables.
What is the height in inches if the area is 27 inches?
Any positive number that you like.
Can height be negative?
No, height cannot be negative. Height is a measurable distance from the base of an object or person to the top, and it is always expressed as a positive value. A negative height would not have any physical meaning in the context of measurement.
What is the base of a square pyramid if the height is 5 ft?
The base can have any positive value.
What is correlation in science?
In science, positive correlation is a general positive slope in something. Often times this is represented with a graph, using many points of data, for instance, height vs age would be a positive correlation. The meaning of positive correlation in both science and math are very, very similar. Only the scenarios they are used in differ.
What is a Correlation example in real life?
Positive Correlation- Age - Amount of medical conditions Negative Correlation- Television Watching- Grades No Correlation- Height of a person- Number of shoes they own Hope this was helpful!
What relationship is there between the length of someones femur bone and their height?
There is a reasonably strong positive correlation.
What can you say about the relationship between a correlation r and the slope b of the least squares line form of data?
You can say that the correlation is positive if and only if the slope is positive. The correlation is zero if and only if the slope is zero. And the correlation is negative if and only if the slope is negative. On the other hand, slope does change when your measurement units change, while correlation does not change. (For example, the correlation between height in inches and weight in pounds will be the same as the correlation between height in centimeters and weight in kilograms, as long as both sets of measurements were taken on the same observations.)
Do the height of a NBA players in relationship to their shoe size represents a negative correlation?
No, the height of an NBA player in relationship to his shoe size does not represent a negative correlation. The two actually represent a positive correlation. As the NBA player increases in size, so will his shoe size.
What is a no correlation graph?
There are three types of correlation: positive, negative, and none (no correlation).Positive Correlation: as one variable increases so does the other. Height and shoe size are an example; as one's height increases so does the shoe size.Negative Correlation: as one variable increases, the other decreases. Time spent studying and time spent on video games are negatively correlated; as the your time studying increases, time spent on video games decreases.No Correlation: there is no apparent relationship between the variables. Video game scores and shoe size appear to have no correlation; as one increases, the other has no effect. A No Correlation graph would show this.

Correlation between eye color and height?
there is none.
What correlation exist between the length of the femur and body height?
Multiplying the length of the femur by 2. 6 and adding 65 to it should be roughly the person's body height in centimeters. However, the sex and race of the person can affect this relationship between the femur and body height.
What is positive correlation and negative correlation?
Positive correletion between x and y means that x=ay+b, with a>0 so tha as y increases, so does the x. Now, negative correlation is the same, but with a<0 so that as y increases, x decreases. You have to be careful with the value of correlation coefficient it takes values in [-1,1]. values near 1(or -1) mean strong positive(or negative for -1) linear relation between x and y.

What is your foot size if your height is 5 foot and 5 inches?
There is no way to say exactly how tall you will be from your foot size. But there are studies that show that there is a positive correlation between foot size and height. In general, a larger person will have a larger foot to support the weight and movement. https://www.statcrunch.com/5.0/viewreport.php?reportid=35115You can not go by observation alone, you must do a scientific study with a large number of people.
