CHARACTERISTICS OF A GOOD AVERAGE:

Answer. The distance meter is used for accurately determining the distance of an object without contact by way of a laser. The distance meter is frequently used in the industrial sectorand especially with professions relating to construction, such as architecture, surveying, carpentry, masonry, locksmiths, etc.

It should be rigidly defined. It should be simple to understand & easy to calculate. It should be based upon all values of given data. It should be capable of further mathematical treatment.

• Average is the easiest method to calculate.
• It should be rigidly defined.
• It should be representative of the entire series.
• It should have capable of further algebraic treatment.
• It should not be affected by the extreme values of the observation or series.

When you have a symmetrical distribution for continuous data, the mean, median, and mode are equal. In this case, analysts tend to use the mean because it includes all of the data in the calculations. However, if you have a skewed distribution, the median is often the best measure of central tendency.

There are three main measures of central tendency: the mean, the median and the mode. When data is normally distributed, the mean, median and mode should be identical, and are all effective in showing the most typical value of a data set.

The main purpose for obtaining a measure of central tendency is to find a single value that will serve as the representative of the entire distribution of scores. Usually, this value is the average of the scores, which could be the mean, median, or the mode.

The mean is usually the best measure of central tendency to use when your data distribution is continuous and symmetrical, such as when your data is normally distributed. However, it all depends on what you are trying to show from your data.
