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.
Raw sweet potatoes are mostly starchy fibers, but they also contain an enzyme that will break down the starch into sugar at certain temperatures. According to food scientist Harold McGee, this enzyme happens to work best when the sweet potato is between 135Â°F and 170Â°F.
