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 mean size and the standard deviation from that mean can be obtained directly from the statistics of the distribution. Here, the (absolute) standard deviation (or âhalfwidthâ) of the distribution can be compared to the mean, and a relative polydispersity = standard deviation / mean can be obtained.
