A witness, who has special training, education, or experience in a particular science, profession or calling, may be allowed to express an opinion in addition to giving testimony as to facts. You are not bound, however, by such an opinion. In determining the credibility and weight to be given such opinion evidence, you may consider, among other things, the education, training, experience, knowledge, and ability of that witness, the reasons given for the opinion, the sources of the witness’ information, together with the factors already given you for evaluating the testimony of any other witness.
