The graphs shown below demonstrate the shapes of various sets of data. Males generally deposit fat around waists and abdomens producing an "apple shape" due to the lack of estrogen.

Impact on health[ edit ] According to the Heart and Stroke Foundation of Canadathose people with a larger waist apple shaped have higher health risks than those who carry excess weight on the hips and thighs pear shaped. Depending on the BMI, a body may be referred to as slim, overweight, or obese.

People with apple shaped bodies who carry excess weight are at greater risk of high blood pressureType 2 diabetes and high cholesterol.

Because the female pelvis is flatter, more rounded and proportionally larger, the head of the fetus may pass during childbirth. Wide shoulders, a muscular upper body and well-developed upper-arm muscles are all traits closely associated with masculinitysimilarly to other specifics of the male sex, like beards.

The hip, waist, and shoulder sections are relatively similar. The female body is significantly narrower in the waist both in front view and profile view.

The mean typically gets pulled toward the tail, and is less than the median. There may be exceptions to the this last statement. Skeletal structure[ edit ] Skeletal structure frames the overall shape of the body and does not alter much after maturity.

There may be exceptions to the this last statement.

These traits are seen more sexually attractive to women and also associated with higher intelligence, good leadership qualities and better health.

Here are some examples of distributions and shapes. A bell shaped graph bell curveis a frequency distribution that resembles the outline of a bell when plotted on a graph. Prominent muscles of the body include the latissimus dorsi, trapezius, pectoral muscles muscles critical for a strong erect posture as well as biceps and triceps in the arms and quadriceps and hamstrings in the thighs.

Not all symmetric graphs, however, have this shape see Symmetric U-shaped below. These graphs are also symmetric. For example, a distribution of analyses of a very pure product would be skewed, because the product cannot be more than percent pure. Notice in the boxplot how each section is of equal length: The supplier might be producing a normal distribution of material and then relying on inspection to separate what is within specification limits from what is out of spec.

The "tail" of the graph is pulled toward higher positive numbers, or to the right. The bimodal distribution looks like the back of a two-humped camel. Hence females generally have wider hips, permitting childbirth. Notice in the boxplot how each section is of equal length: Distributions that are skewed have more points plotted on one side of the graph than on the other.

Distributions that are skewed have more points plotted on one side of the graph than on the other. The relationship between skew and the relative size of the mean and median led the statistician Pearson to propose the following simple and convenient numerical index of skew: Stratification often reveals this problem.

Because there are many peaks close together, the top of the distribution resembles a plateau. Distributions with fewer observations on the right toward higher values are said to be skewed right; and distributions with fewer observations on the left toward lower values are said to be skewed left.

The outputs of many processes—perhaps even a majority of them—do not form normal distributions, but that does not mean anything is wrong with those processes.

Many terms or classifications are used to describe body shape types: Symmetric U-shaped - as mentioned above, a symmetric graph forms a mirror image of itself when reflected in its vertical center line.

In a comb distribution, the bars are alternately tall and short. There are no clear peaks in these graphs, since each data entry appears the same number of times in the set. Otherwise, a normal distribution would have a kurtosis of 3.

Body posture and gait[ edit ] Body shape has effects on body posture [16] and gaitand has a major role in physical attraction. 3. single peak at the center is called bell shaped distribution. Note: A bell shaped graph (bell curve), is a frequency distribution that resembles the outline of a bell when plotted on a graph.

Body language affects how others see us, but it may also change how we see ourselves. Social psychologist Amy Cuddy argues that "power posing" — standing in a posture of confidence, even when we don't feel confident — can boost feelings of confidence, and might have an impact on our chances for success.

Mathematics K–12 Learning Standards. Washington formally adopted the Mathematics and English Language Arts K–12 Learning Standards, also referred to as “the standards". Definition Standard normal distribution.

The simplest case of a normal distribution is known as the standard normal maxiwebagadir.com is a special case when = and =, and it is described by this probability density function: = −The factor / in this expression ensures that the total area under the curve () is equal to one.

The factor / in the exponent ensures that the distribution has unit. Normal. A common pattern is the bell–shaped curve known as the “normal distribution.” In a normal distribution, points are as likely to occur on one side of the average as on the other.
