Purpose
Price per unit metrics allow marketers to "calculate meaningful average selling prices within a product line that includes items of different sizes."
Many brands or product lines include multiple models, versions, flavors, colors, sizes, or — more generally – stock-keeping units (SKUs). Brita water filters, for example, are sold in a number of SKUs. They are sold in single-filter packs, double-filter packs, and special banded packs that may be restricted to club stores. They are sold on a standalone basis and in combination with pitchers. These various packages and product forms may be known as SKUs, models, items, and so on.
The information gleaned from a price per statistical unit can be helpful in considering price movements within a market. Price per statistical unit, in combination with unit price averages, provides insight into the degree to which the average prices in a market are changing as a result of shifts in 'mix' – proportions of sales generated by differently priced SKUs – versus price changes for individual items. Alterations in mix – such as a relative increase in the sale of larger versus smaller ice cream tubs at retail grocers, for example – will affect average unit price, but not price per statistical unit. Pricing changes in the SKUs that make up a statistical unit, however, will be reflected by a change in the price of that statistical unit.

Famous quotes containing the word purpose:
“I beg to assure you that I have never written you, or spoken to you, in greater kindness or feeling than now, nor with a fuller purpose to sustain you, so far as in my most anxious judgement, I consistently can. But you must act.”
—Abraham Lincoln (1809–1865)
“The United States is the only great nation whose government is operated without a budget. The fact is to be the more striking when it is considered that budgets and budget procedures are the outgrowth of democratic doctrines and have an important part in developing the modern constitutional rights.... The constitutional purpose of a budget is to make government responsive to public opinion and responsible for its acts.”
—William Howard Taft (1857–1930)
“Culture is the tacit agreement to let the means of subsistence disappear behind the purpose of existence. Civilization is the subordination of the latter to the former.”
—Karl Kraus (1874–1936)
