The unit of measurement for this variable is INCHES.
A few possible values for this first quantitative variable are 2IN. 2 ½ IN. and 3IN. Slide3
Second quantitative variable is Pinky Length
The unit of measurement is INCHES.
A few possible quantitative variables are 2IN. 3IN. & 2 ½IN.Slide4
Purpose: Find if correlation exists between the pinky finger and ear for a particular person.
For the study we randomly selected and measured a pinky and an ear from each person using a measuring tape. Slide5

Conclusion
The study did show a
significant correlation
between pinky length and ear length. Our correlation coefficient is above this (at 0.862) and qualifies as being statistically significant. (Critical Value was .325)So in answer to our question there is a significant correlation between pinky lengths and ear lengths.
