Grouped Products are simple products to a single parent product. This allows the customer to add products from a range, or a couple of products from within a range, to their cart on one page instead of navigating to several different pages to do so.
Often they will produce several similar products that appeal to different customers. A collection of such products is known as a "product group" or "product range".
Good examples of product groups include: Apple's range of laptops (MacBook), desktops (iMac), tablets (iPad), smartphones (iPhone) and wearables (iWatch)
