Some examples of correlation coefficients are the relationships between deer hunters and deer in a region, the correlation between the distance a golf ball travels and the amount of force striking it and the relationship between a Fahrenheit and a Celsius temperature value. Correlation coefficients are measured within the range of -1 and 1. A stronger absolute value indicates a stronger linear relationship between the two variables.
A correlation coefficient that is equal to 0 demonstrates the weakest possible linear relationship between the components being examined. A value of either -1 or 1 represents the strongest possible correlation.
The correlation is negative if one variable decreases as the other grows. This could be exemplified by the deer and deer hunter relationship. The number of deer will most likely decrease as the number of deer hunters increases. In the case of the Fahrenheit and Celsius temperature relationship, the correlation will always be positive because as one variable increases, so does the other.

Full Answer >When drawing a Venn diagram to compare and contrast hurricanes and tornadoes, all their properties should be listed. Their similarities should be listed where the circles overlap, and their differences should be listed where the circles do not overlap.
Full Answer >One column in a hundredths grid is equal to one column in a tenths grid because in each case, the selected column composes one-tenth of the grid in total. The number of blocks is different, but the proportion of space filled is the same.
Full Answer >A histogram is a graphical representation of quantitative data. It has a continuous number line on the horizontal axis that is grouped into ranges, or class intervals. The quantity for each range is displayed as different column heights.
