What is the advantage of a distance-time graph?

What is the advantage of a distance-time graph?

(i) It tells us about the position of the body at any instance of time. (ii) From the graph, we can see the distance covered by the body during a particular interval of time. (iii) It also gives us information about the velocity of the body at any instance of time.

What is area under curve?

In the field of pharmacokinetics, the area under the curve (AUC) is the definite integral of a curve that describes the variation of a drug concentration in blood plasma as a function of time (this can be done using liquid chromatography–mass spectrometry).

What is area under normal curve?

The total area under the normal curve is equal to 1. The probability that a normal random variable X equals any particular value is 0.

How do you find the area under a normal curve?

To find a specific area under a normal curve, find the z-score of the data value and use a Z-Score Table to find the area. A Z-Score Table, is a table that shows the percentage of values (or area percentage) to the left of a given z-score on a standard normal distribution.

How do you find the area under the Z score?

To find the area between two points we :

1. convert each raw score to a z-score.
2. find the area for the two z-scores.
3. subtract the smaller area from the larger area.

How do you find the area corresponds to Z?

Area to the Right of a Positive z Score Since the total area under the bell curve is 1, we subtract the area from the table from 1. For example, the area to the left of z = 1.02 is given in the table as . 846. Thus the area to the right of z = 1.02 is 1 – .

How do you find the Z value?

The formula for calculating a z-score is is z = (x-μ)/σ, where x is the raw score, μ is the population mean, and σ is the population standard deviation. As the formula shows, the z-score is simply the raw score minus the population mean, divided by the population standard deviation.

What is the another term of Z table?

A z-table, also called the standard normal table, is a mathematical table that allows us to know the percentage of values below (to the left) a z-score in a standard normal distribution (SND). When the mean of the z-score is calculated it is always 0, and the standard deviation (variance) is always in increments of 1.
