configuration and location of stop lines. Model Calibration The assignment guidelines provide the following observed speed data to calibrate the model: “The average free flow speed was found to be 45km/hr” The idea of calibration is to adjust the model to achieve similar modelled speed results as observed within the field. Free flow speed is the average speed a road user would travel if there were no congestion in normal conditions. The free flow speed occurs when density and flow are equal to zero.

mode. Mean is the average of all the observations. Median is the middle most value of the observations and mode has the maximum frequencies. Let us see the use of statistics in daily life. Use of Satistics in Daily Life :mean Mean can be used to see the average mark of the class obtained. This average helps to see how many students are above average‚ how many are average students and how many are below averages. The teacher tries to help the average and below average students to score

Godden and Baddeley (1975) Godden and Baddeley under took a field experiment in which they investigated if being in the same environment when learning/remembering something affects their recall in appose to being in a different environment from where the words are learnt. They did using an independent group design. Godden and Baddeley found 18 deep-sea divers whom were given 38 unrelated two or three syllable words‚ they all

Analytical tool An analytical tool is something used to analyze or "take a closer look at" something. It is normally a way to review the effectiveness of something. For example‚ Google offers a free web analytics tool that is used by Web Masters to track visitors on a given site. It allows Web Masters to see where visitors are coming from‚ how long they stay‚ what links they are reviewing‚ etc. Analytic Tool help with Tracking and Reports!
