The basics: Chapter 1

A set of flashcards covering key concepts related to DMS graphs, relationships between data items, and scientific notation.

What is the purpose of graphs in DMS (Data Management System)?

Graphs, such as blood velocity graphs, are used to represent data visually.

What defines unrelated items in a data context?

Unrelated items are two items that are not associated with each other, e.g., hair color vs shoe size.

What does it mean for two items to be related or proportional?

Related items are those that are associated or affiliated, but the nature of their relationship does not need to be specified.

What is a directly related or directly proportional relationship?

When one item increases, the other also increases, e.g., clothing size is directly proportional to one's weight.

What defines an inversely related or inversely proportional relationship?

When one item increases while the other decreases, e.g., basketball score is inversely related to skill.

What is a reciprocal relationship?

A reciprocal relationship occurs when two numbers are multiplied together to result in one; they are inverse of each other.

Why is it necessary to include units in numerical answers?

A comprehensive numerical answer requires a unit to provide context to the number.

What is unit conversion?

Unit conversion is the process of changing from one unit of measurement to another.

What does a positive exponent represent in scientific notation?

A positive exponent represents a value greater than 10.

What is the value of an exponent of zero in scientific notation?

An exponent of zero represents a value between 1 and 10, e.g., 1.0.

What does the notation 1.24 x 10^-3 represent?

It represents a number in scientific notation, specifically 0.00124.

What are complementary metric units?

Complementary metric units refer to units of measurement that are related to each other in terms of magnitude and can be converted from one to another.

Complementary Metric Units: Pairs/Prefixes/ Abbreviations

Metric System: Exponent/ Prefix/ Symbol/ Meaning

What is an appropriate unit for area?

Square yards- area is measured in units of length squared.

What is not an appropriate unit for volume?

Cm. Volume is measured in units of length cubed.

What happens to the nyquist limit when the PRF increases? And decreases?

If PRF increase, NL increases, if PRF decreases, NL decreases

What happens to the PRF when the Nyquist Limit increases? And decreases?

If NL increases, PRF increases. If NL decreases, PRF decreases.
