The previously discussed rectangular distribution is a reasonable default model in the absence of any other information. But, if it is known that value of the quantity in question is more likely near the mean of the interval and less likely near the limits, a triangular distribution is a better model. A triangular probability density function is often used when making measurements using analog devices. Consider the measurement of the rectangular block using a steel rule as shown in the image. A general rule when making measurements with an analog device is to read to the nearest division mark.
