| 41. | The arithmetic mean of the two limiting distances is the length of the semi-major axis " a ".
|
| 42. | Therefore, the median is 4 since it is the arithmetic mean of the middle observations in the ordered list.
|
| 43. | In elementary schools conduct grades also are not counted in the arithmetic mean while in secondary schools they are.
|
| 44. | Because of this the usual sample mean ( arithmetic mean ) is a biased estimator of the true mean.
|
| 45. | For real numbers, the arithmetic mean is a Fr�chet mean, using the usual Euclidean distance as the distance function.
|
| 46. | :2 ) A weighted arithmetic mean is useful when some data points need to be weighted more than others.
|
| 47. | It is more apparent that the harmonic mean is related to the dual of the arithmetic mean for positive inputs:
|
| 48. | "Average " is the arithmetic mean; " median " is the figure in the middle of the series of numbers.
|
| 49. | Since the variance is always e " 0 the contraharmonic mean is always greater than or equal to the arithmetic mean.
|
| 50. | In this case, the arithmetic mean of the two middlemost terms is ( 2 + 6 ) / 2 = 4.
