Final answer:
Random errors are the statistical variability of the measured number and can be caused by various factors such as irregularities in the object being measured. Accuracy, on the other hand, refers to how close the average value is to the actual value.
Step-by-step explanation:
Random errors are the statistical variability of the measured number. They vary from one observation to another and can be caused by irregularities in the object being measured, limitations of the measuring device, or other factors that affect the outcome. Random errors can be minimized by taking multiple measurements and averaging the results. Accuracy, on the other hand, refers to how close the average value is to the actual value.
