Cumulative frequency specifies how many data values are of a particular number or smaller. For example, in the data set {1, 1, 2, 2, 3, 3, 4, 4, 4, 5, 26}, the cumulative frequency for the value 4 is nine, since there are nine values in the set that are 4 or less.
More starch is removed from a cut potato than a whole peeled potato, because a greater surface area is exposed on cut potatoes. Soak them in cold water for as long as a few hours to remove more starch than by rinsing alone. You'll notice cloudiness and starch at the bottom of the bowl.f you simply want to reduce the amount of starch in your diet, discard the starch and water immediately after soaking the potatoes. But save the starch when you want to make extra crispy hash browns, latkes or home fries.
Potatoes are also a good source of potassium. All potatoes are potassium rich, Jarzabkowski said. They have even more potassium than a banana, and a lot of it is found in the [potato's] skin.. She noted that the outer potato peel also contains a good deal of fiber.n a potato, those water-soluble nutrients include B-complex vitamins, vitamin C, potassium and calcium. As much as 80 percent of a potato's vitamin C may go down the drain if you boil the vegetable. The same thing can happen with peeled potatoes that are left to soak, a method used to stop darkening.
