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.
All potatoes actually contain low levels of natural toxins called glycoalkaloids. The toxins are produced by the potato in response to stress, which is green potatoes, which have been exposed to UV light, can contain high levels. Potatoes that have a lot of bruising, sprouts or eyes, or that taste bitter may also have high levels of toxins. Green potatoes really can make you sick. Glycoalkaloids can cause severe stomachache and even death, in rare cases, and it's not destroyed by cooking.
