[QUOTE="35years, post: 2756690, member: 60822"] [B]Further investigation[/B] into whether the supervised SPORH was "observed" in an unbiased, unmanipulative way. And was truly representative of a typical day. Anyone with knowledge of statistical studies will agree that an unrepresentative study conducted not at random will result in extremely unreliable data. Not to mention the observer being biased and affecting the driver. The margin of error in such a small, unrepresentative sample would be so large that any conclusions based on the results would have to be seen as at least spurious if not completely unreliable. in addition to throwing out the results on rainy, snowy, icy or heavy and light days. Too many variables uncontrolled. Unrepresentative, small, not random sample. Implementation and manipulation by a biased observer. [/QUOTE]
