CHILD DEVELOPMENT PEDAGOGY

Detailed explanation-1: -We can find both the mean and standard deviation by eye on a normal curve. The mean is the center of symmetry for the curve. To find , start at the center of the curve and run a pencil outward.

Detailed explanation-2: -The mean (the perpindicular line down the center of the curve) of the normaldistribution divides the curve in half, so that 50% of the area under the curveis to the right of the mean and 50% is to the left. Therefore, 50% of testscores are greater than the mean, and 50% of test scores are less than the mean.

Detailed explanation-3: -A normal distribution is a type of continuous probability distribution in which most data points cluster toward the middle of the range, while the rest taper off symmetrically toward either extreme. The middle of the range is also known as the mean of the distribution.

Detailed explanation-4: -The exact middle or center of a bell curve, if the data is distributed normally, is called the mean. The mean is the mathematical average. In a normal curve, the mean is also equal to the mode and the median of the data. The mode is the value which occurs the most often in the distribution.

Detailed explanation-5: -A normal distribution can be used to describe a variety of quantitative variables. A normal distribution curve is bell-shaped. The mean, median, and mode are equal and are located at the center of the distribution. A normal distribution curve is unimodal ( it has only one mode).
