Ronnie Hinson has penned the lyrics to some of Southern Gospel music's greatest songs. The Lighthouse is one such song that has indeed stood the test of times. It bears testimony to the power of God's Holy Spirit and His Word to lead wayward souls to the safe harbor of Christ's Grace.
The average absolute deviation (or mean absolute deviation) of a data set is the average of the absolute deviations from a central point. It is a summary statistic of statistical dispersion or variability.
The standard deviation of a random variable, statistical population, data set, or probability distribution is the square root of its variance. It is algebraically simpler, though in practice less robust, than the average absolute deviation.his means that most men (about 68%, assuming a normal distribution) have a height within 3 inches of the mean (67â73 inches) â one standard deviation â and almost all men (about 95%) have a height within 6 inches of the mean (64â76 inches) â two standard deviations.
