Definition. A tumor is an abnormal growth caused by the uncontrolled division of cells. Benign tumors do not have the potential to spread to other parts of the body (a process called metastasis) and are curable by surgical removal.
Fine Focus: This is the knob used to fine tune the focus on the specimen. It is also used to focus on various parts of the specimen. Generally one uses the coarse focus first to get close then moves to the fine focus knob for fine tuning. Field of View: Sometimes abbreviated FOV, it is the diameter of the circle of light that you see when looking into a microscope.
The variable in prime focus, fine motor skills, was found to only have a significantly positive correlation with the number of errors made on the d2. Here one must pay close attention to the poling of the variables; pupils with deficits in fine motor skills make, on the average, more mistakes on the d2. Furthermore, the total score on the d2 correlated, as expected, positively with the number of errors and the difference between the total score and the errors.
