In each good inference there is always observations to create the inference. Good data makes good inference.To have good observations and data you have to have a lot of detail in what you say and pay attention to your data and what you get. For the soil lab you had to pay close attention to the amount of pH of the different kinds of dirt and right the exact amount of pH or close to it beacuse if you dont you get the rong answer so good data and inference are important for the.For the gun lab you have to pay close atteion to the bullets other wise you will get the wrong bullet. When you are doing the fiber lab you have to pay attenuation to the microscope or when you are burning the fibers you have to pay attention to to the flame and how it burns.

It is hard to be precise when the information may not be true like in the soil its hard to test the pH because the numbers on the computer don't stop they just keep chaining and in the bullet lab it is hard when it might not be the right bullet because there were lots of bullets that were almost the same.In the fabric it was hard to describe how they fabric looked because of the microscope and the microscope was very wired and was hard to get focused so we could see a good picture.

you can rely on known data well in the guns lab we looked at the diagrams and power point to find out about what to do and thing like that we had to generate our own data in the fiber lab we had to describe what the smell was of the fiber that was burned and we had to check the ph of the dirt when we did the soil lab.
