It is important because if the sample size is smaller, outliers could skew the data more than if it was large.
Paul J. Chirik developed methods associated with chemistry catalysis and transition metals, which may result useful for the development of manufacturing technologies.
<h3>What is catalysis?</h3>
Catalysis refers to the chemical processes that increase the rate of different types of reactions by lowering its activation energy.
Proteins (enzymes) are biological catalysts that increase the rate of chemical reactions in biological systems.
Catalysis may be reached by using transition metals (e.g., actinium and rutherfordium), which result useful in the development of manufacturing technologies.

Answer:
Is this an actual question that you had for school?
Explanation:
<h3>Further explanation</h3>
Given
the structure of the alkanes
Required
match the image to the name
Solution
Alkanes are saturated hydrocarbons with all of the carbon bonds being single bonds
General formula:

If we look at the picture, we define the black atom as Carbon and the branch is Hydrogen
To determine the name of the alkane, all we have to do is count the number of Carbon atoms
Butane : C₄H₁₀ : 4 C atoms
Methane : CH₄ : 1 C atom
Ethane : C₂H₆ : 2 C atoms
Propane : C₃H₈ : 3 C atoms
