precision is being very careful and doing something in a concentrated way
accuracy is the ability to continually do something nearly identical everytime

Accuracy is a measure of how close your measurement comes to the accepted answer. Precision is a measure of how close a series of measurements are to each other.

there are two types of error in scientific measurements.
1. random error, which is amenable to statistical analysis so that if you make enough measurements you can determine the mean and standard deviation for that measurement. precise measurements have low random error.
2. systematic error, which is not random, and due to uncontrolled factors or poor experimental design. accurate measurements have low systematic error.

precision is doing something to try and become accurate.
