Outliers existing in a data set will have the greatest impact on __________. A. the mean B. the median C. the mode D. the middle
Answers
Answer:
Outliers existing in a data set will have the greatest impact on :
option: A is the correct answer.
A. The mean.
Step- by- step explanation:
We know that an outlier is a data value or the data point that stands out of the rest of the data points of the set i.e. it either attains a too high or too low value as compared to other data points.
Hence, the outlier will effect the mean of the data set.
( Since, when a too low value is present in the set then after removing that value the mean of remaining elements or data points will increase after removing the outlier.
For example if we have data set as:
1 30 34 39 41 45
Then mean of the set is:
and on removing 1 from the set we get:
Hence, we see that the mean is increased.
Similarly, if there is a data value which is too high then after removing that element the mean of the remaining data points will decrease )

Answer : Salinity tolerance
Explanation :
The important characteristics for the plants which are found in salt water wet lands is salinity tolerance.
Salinity tolerance is the salt tolerance of crops in the wet lands which gives maximum salt level that a crop can tolerate without losing its productivity.
Although it may get affected negatively at higher levels of exposure. The salt level is often measured as the soil salinity or else the salinity of the irrigated water.

By looking at the periodic table (values will be to 3 significant figures [2 for hydrogen though]):
Molar mass (M) of 1 mole of Carbon = 12.0 g/mol
Molar mass (M) of 1 mole of Hydrogen = 1.0 g/mol
Molar mass (M) of 1 mole of Oxygen = 16.0 g/mol
So the molar mass is essentially the relative atomic mass (RAM), but molar mass has a unit, but RAM doesn't (it is a ratio).
Given the formula is C6H12O6 (without putting the numbers as subscripts), we can calculate as follows:
M (C6H12O6) = (6 x 12.0) + (12 x 1.0) + (6 x 16.0)
= 72.0 + 12.0 + 96.0
= 180.0 g/mol
Hope it's right :D
Final answer:
The molar mass of glucose, also known as blood sugar and dextrose, is calculated by summing the respective molar masses of carbon, hydrogen, and oxygen in one molecule of glucose. It is approximately 180.16 g/mol.
Explanation:
The molar mass refers to the mass, in grams, of one mole (6.022 x 1023 molecules) of a substance. For glucose (C6H12O6), we calculate it by summing up the molar masses of individual elements, multiplying each by their respective number of atoms in one molecule of glucose.
The molecular masses of carbon (C), hydrogen (H), and oxygen (O) are approximately 12.01 g/mol, 1.008 g/mol, and 16.00 g/mol respectively. So the molar mass of glucose is calculated as follows: (6*12.01 g/mol) + (12*1.008 g/mol) + (6*16.00 g/mol) = 72.06 g/mol + 12.10 g/mol + 96.00 g/mol = 180.16 g/mol.
So, the molar mass of glucose, C6H12O6, also known as blood sugar and dextrose, is approximately 180.16 g/mol.

Answer: Plasma
Explanation:
There are four states of matter
Solid state : It is a state in which the particles are closely packed and does not have any space between them. This state has a definite shape and volume.
Liquid state : It is a state in which the particles are present in random and irregular pattern. The particles are closely arranged but they can move from one place to another. This state has a definite volume but does not have a fixed shape.
Gaseous state : It is a state in which the particles are loosely arranged and have a lot of space between them.This state has indefinite volume as well as shape.
Plasma is the state of matter in which the gas is present in ionized form and is at high temperatures. Thus due to the presence of charged particles, they allow electric current to pass through them and are good conductors of electricity.
