Normal Distribution Explained Simply Part 2 Youtube I describe the standard normal distribution and its properties with respect to the percentage of observations within each standard deviation. i also make ref. The normal, or gaussian, distribution is the most common distribution in all of statistics. here i explain the basics of how these distributions are created.
Normal Distribution Part 2 Youtube *** improved version of this video here: youtu.be tdlcbrlzbosi describe the standard normal distribution and its properties with respect to the perce. A standard normal distribution has the following properties: mean value is equal to 0; standard deviation is equal to 1; total area under the curve is equal to 1; and; every value of variable x is converted into the corresponding z score. you can check this tool by using the standard normal distribution calculator as well. if you input the mean. Step 1: sketch a normal distribution with a mean of μ=30 lbs and a standard deviation of σ = 5 lbs. step 2: a weight of 35 lbs is one standard deviation above the mean. add the percentages above that point in the normal distribution. 13.5% 2.35% 0.15% = 16%. step 3: since there are 200 otters in the colony, 16% of 200 = 0.16 * 200 = 32. The normal distribution is a continuous probability distribution that plays a central role in probability theory and statistics. it is often called gaussian distribution, in honor of carl friedrich gauss (1777 1855), an eminent german mathematician who gave important contributions towards a better understanding of the normal distribution.
