How do you do mode?
To find the mode, or modal value, it is best to put the numbers in order. Then count how many of each number. A number that appears most often is the mode.
How do you solve mean?
How to Find the Mean. The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.

How do you find the mean median and mode of Class 9?
Median = Size of (n+12)th item. Median = average of n2th and n+22th item. The Mode: The mode is that value in a series of observation which occurs with greatest frequency.
What is matter and its properties?
Matter is anything that occupies space and has mass. The three states of matter are solid, liquid, and gas. Extensive properties depend on the amount of material and include mass and volume. The ratio of two extensive properties, mass and volume, is an important intensive property called density.
What are important properties of materials?

- Density.
- Ductility / Malleability.
- Elasticity / Stiffness.
- Fracture Toughness.

What is mean by discovered?
to see, get knowledge of, learn of, find, or find out; gain sight or knowledge of (something previously unseen or unknown): to discover America;to discover electricity. to notice or realize: I discovered I didn’t have my credit card with me when I went to pay my bill. Archaic. to make known; reveal; disclose.

Is Median always between mean and mode?
The mode is always less than the median, which is less than the mean, if the data distribution is skewed to the right. …
What is the relationship between mean median and mode?
Empirical Relationship between Mean, Median and Mode In case of a moderately skewed distribution, the difference between mean and mode is almost equal to three times the difference between the mean and median. Thus, the empirical mean median mode relation is given as: Mean – Mode = 3 (Mean – Median)
What is the property of median?
In geometry, a median of a triangle is a line segment joining a vertex to the midpoint of the opposite side, thus bisecting that side. In the case of isosceles and equilateral triangles, a median bisects any angle at a vertex whose two adjacent sides are equal in length.
What is the importance of mode?
Mode is most useful as a measure of central tendency when examining categorical data, such as models of cars or flavors of soda, for which a mathematical average median value based on ordering can not be calculated.
