Hello,

 

I'm interested in the relationship of the ratios of pregnancy length, amount of time before the infant is independent of the parent and the average life span.

 

For example, a dog is pregnant for 9 weeks, the puppy weens for 8-12 weeks, and then lives for 10-12 years.

 

Does anyone know which animals (humans included - i know it's difficult to decide when a child is independent from it's parents) have the longest/shortest pregnancy in relation to life span.

 

Also, which animal spends the most/least time dependent on it's parents in comparison to it's life span.

 

Thanks!

1. The first point is to use standard terminology.
   
2. Google something such as gestation lifespan.
   
3. Find a website with data in tables like this one.
   
4. Copy and paste the whole table into a spreadsheet.
   
5. Replace cell contents with average values (round to whole numbers).
   
6. Create an XY (Scatter) chart of the data.
   
7. For best viewing of the data, use the log-log format.
   
8. Choose a trendline.
   
9. Display the trendline's equation on the chart.
   

Come back with any questions on how to do this.
