In regard to evidentiary matters, it is within the district court's discretion to determine whether or not evidence is relevant and admissible. District courts are vested with great latitude in ruling on the admissibility of expert testimony. Absent a showing of an abuse of discretion, we will not overturn a district court's determinations on evidentiary matters. State v. Hocevar, 2000 MT 157, ¶ 54, 300 Mont. 167, 7 P.3d 329 (citation and quotation marks omitted).
