A report noted that the correlation between fish activity and water temperature (Fahrenheit) is 0.86. If the temperature were measured in degrees Celsius how would the correlation change? Note F= 9/5 C + 32.   r = 47.7  (5/9 of 86)   r= 79.77  { 5/9 (86) + 32}   r= 0.86 no change   it would depend on how many zero temperature (F) observations need the actual data.
