Statistics – Measures of Central Tendency In Statistics, measures of central tendency are mainly three namely; the median, the mode, and the mean. Every category different statistic measurement. The mode is the most appearing figure in a distribution.

Linear motion Solve these linear motion questions. Linear Motion We provide high quality tests and answers. Both speed and velocity determine the distance and displacement covered within a given unit of time. A passenger train traveling at 25km/h is moving in the same direction as a truck traveling at 30km/h.
