The person above me sounds more correct, but let me try. The data is reliable because the more force, the more acceleration the object will have. It increases by one every time you add fifty more newtons. This shows it's reliable
The data above would be precise and/or accurate if they were subjected to multiple trials. Considering only 1 trial was done per the Level of IV (the Force applied on mass in Newtons), the precision cannot be calculated. The accuracy can be only calculated by subjecting data under uncertainty. But still, the data is not reliable. Do more trials, see what you come up with.
