Other costing methods include last in, first out and first in, first out, or LIFO and FIFO respectively.Ī manufacturer purchases 20,000 units of a product at $1 each, 15,000 at $1.15 each and 5,000 at $2 each. This number goes into the calculation for the cost of goods sold. In some industries where quantities are mixed or too numerous to count, the weighted average method is useful. Weighted average is one means by which accountants calculate the costs of items.

It is an important tool in accounting for stock fluctuations, uneven or misrepresented data and ensuring similar data points are equal in the proportion represented. Weighted averages are commonly used in statistical analysis, stock portfolios and teacher grading averages. What is weighted average?Ī weighted average is the average of a data set that recognizes certain numbers as more important than others.

In this article, we explore how to calculate weighted average using two methods. The accuracy of the numbers you arrive at with this method is determined by the weight you give specific variables in the data set. A weighted average helps the user gather a more accurate look at a set of data than the normal average alone.

Take the child's weight to the nearest 500 g and record.Fix the chart on an even wall with the bottom of the chart touching the floor.Steps for using the Weight-for-Height Wall Chart: The chart is printed on heavy duty laminated paper with an approximate size 140 x 100 cm (approx. The Chart helps in the interpretation of anthropometric measurements through a colour coding system which corresponds to the equivalent Weight-for-Height percentage (W/H %) or Standard Deviation score (Z-score). Using the Weight-for-Height Wall Chart to calculate the Weight-for-Height/Length percentage or Standard Deviation score (Z-score) The range should be written down as such for interpretation. 6.4 and 7.2 are between the columns showing 60% and 70% or between -4 SD and -3SD). Follow these columns up to the top of the table to note the percentage and SD range (e.g.in this case 6.7 kg is between 6.4 and 7.2 kg on the table). On this line find the figure/range corresponding to the weight of the child (e.g.74) making sure that it is horizontal under the other figures on the same line (8.8 8 7.2 and 6.4) Take a ruler (or a piece of card) and place it under the figure (e.g.For 73.8 cm measurement, look for the figure 74). Round the figure to the nearest 0.5cm and look down that column for the figure (e.g. Find the column "Height" on the table.This reference table helps in the interpretation of anthropometric measurements through the Weight-for-Height/Length percentage (W/H %) or Standard Deviation score (Z-score).Įxample: A length of a boy is 73.8 cm and his weight is 6.7 kg.
