In determining whether the trial court was warranted in granting appellees’ motions for summary judgment, we must consider whether the court properly excluded the scientific testimony of appellants’ expert witnesses.

I. Expert Testimony of Dr. Lafferty

At the core of this determination is whether the testimony of James Lafferty was admissible and whether the test he based his opinion upon was reliable.

Appellants retained James Lafferty, a consulting engineer in the areas of mechanical and biomedical engineering, to provide them with an opinion on whether the helmet was a cause of Miller’s injuries. The helmet, which was manufactured in 1981, had been reconditioned by appellee Ace Cleaners & Reconditioners of Athletic Equipment, Inc. prior to being used by appellant. The helmet is designed with an energy-absorbing liner consisting of two bladders, an upper and lower bladder. The lower bladder is to be inflated before the player puts on the helmet. The upper bladder is then inflated through a valve at the top of the helmet. When Lafferty examined the helmet, he found that the valve opening at the top of the helmet had been sealed shut and that the helmet had “zero gauge pressure” in the lower bladder. Although he did not know if there had been any leakage since the accident, Lafferty inflated the lower bladder and rechecked the pressure ten days later. At that time, he found no significant air leakage. Lafferty believed that the lining had not been properly inflated at the time Miller was injured.

Lafferty took the helmet to Capitol Varsity Athletic Equipment, Inc. to test it in accordance with standards established by the National Operating Committee on Standards for Athletic Equipment (“NOCSAE”). The purpose of such testing is to determine the helmet’s shock-absorption properties under various conditions. The NOCSAE standard is a head-protection standard; however, in Lafferty’s opinion, the test can also be used to determine whether a helmet can [610]*610prevent injuries to the neck. In the NOCSAE test, the helmet is mounted on a head form and then dropped from varying heights, with the head form aligned so that impact can occur at the sides, back, top, and front. The “severity index” is then calculated from measurements of acceleration to determine the helmet’s concussion tolerance. If a helmet has a severity index of higher than fifteen hundred, the helmet fails the test.

With Lafferty observing, an employee at Capitol Varsity Athletic Company conducted two partial tests on the helmet in question, dropping it from a height of sixty inches, with impact to the top of the helmet only, since that is where Lafferty believed the point of impact was. First, the helmet was tested with no air added in the lower bladder, which resulted in a severity index of six hundred twenty-four. Next, the lower bladder was inflated to a pressure of 3.5 pounds per square inch, which resulted in a severity index of four hundred seventeen. Lafferty stated that although the helmet passed the test in both instances, the critical fact was that the failure to inflate the lower bladder decreased the energy-absorbing capability by about fifty percent. In conjunction with this finding, Lafferty then noted that the threshold for compressive fracture of the C5 body is about one thousand pounds of force and that the force sustained by Miller’s spine was at the threshold level (otherwise, he would have sustained additional fractures at other locations on the spine). Lafferty concluded that a fifty-percent increase in the energy absorbing capability of the helmet would have attenuated the forces to below the threshold level. Had the helmet been properly inflated, the helmet would have sufficiently absorbed the force of the impact, and the injury would have been avoided.

In deciding whether Lafferty’s testimony was proper, we begin our analysis with a consideration of Evid.R. 702, which governs the admissibility of expert testimony. It provides:

“A witness may testify as an expert if all of the following apply:

“(A) The witness’ testimony either relates to matters beyond the knowledge or experience possessed by lay persons or dispels a misconception common among lay persons;

“(B) The -witness is qualified as an expert by specialized knowledge, skill, experience, training, or education regarding the subject matter of the testimony;

“(C) The witness’ testimony is based on reliable scientific, technical, or other specialized information. To the extent that the testimony reports the result of a procedure, test, or experiment, the testimony is reliable only if all of the following apply:

[611]*611“(1) The theory upon which the procedure, test, or experiment is based is objectively verifiable or is validly derived from widely accepted knowledge, facts, or principles;

“(2) The design of the procedure, test, or experiment reliably implements, the theory;

“(3) The particular procedure, test, or experiment was conducted in a way that will yield an accurate result.”

There is no question that Dr. Lafferty is a qualified expert who testified about a subject beyond the knowledge of lay persons. Evid.R. 702(A) and (B). Thus, at issue in this case is whether Lafferty’s testimony complied with the requirements of Evid.R. 702(C), ie., whether his opinion was reliable. In making this determination, our inquiry focuses on whether the principles and methods Lafferty employed to reach his opinion are reliable, not whether his conclusions are correct. See Staff Notes to Evid.R. 702. Additionally, to be admissible, the expert testimony must assist the trier of fact in determining a fact issue or understanding the evidence. Id.; State v. Boston (1989), 46 Ohio St.3d 108, 118, 545 N.E.2d 1220, 1231; State v. Bidinost (1994), 71 Ohio St.3d 449, 454, 644 N.E.2d 318, 323.

In Daubert v. Merrell Dow Pharmaceuticals, Inc. (1993), 509 U.S. 579, 113 S.Ct. 2786, 125 L.Ed.2d 469, the United States Supreme Court discussed the question of when expert scientific testimony is relevant and reliable. In Daubert, the court was faced with the issue of whether certain scientific evidence was admissible in a birth defects case. The trial court, in excluding the expert testimony, relied upon Frye v. United States (D.C.App.1923), 293 F. 1013, which held that an expert’s opinion is inadmissible unless it has gained “general acceptance” in the relevant scientific community. Id. at 1014. The Daubert court expressly rejected this argument and reversed the granting of summary judgment. Instead, it held, under Fed.R.Evid. 702, that expert scientific testimony is admissible if it is reliable and relevant to the task at hand. Id. at 589, 113 S.Ct. at 2795, 125 L.Ed.2d at 480. To determine reliability, the Daubert court stated that a court must assess whether the reasoning or methodology underlying the testimony is scientifically valid. Id. at 592-593, 113 S.Ct. at 2796, 125 L.Ed.2d at 482.
