Q

It is a unit system that was created in Great Britain that unified various standards of measurement across the entire country. This system was developed by the
creative minds of early natural philosophers and apothecaries or pharmacists

Q

It is a unit system designed to simplify the way things are
measured, due to the inconsistency of the units used in the English System way before they were unified. Even Great Britain and the US adopted this system.

Q

What are the 2 advantages of writing numbers in scientific notation?

A
  1. It saves space, especially when handling extremely large amounts of data using complicated formulae.
  2. It allows for faster unit conversions.

17
Q

It is the horizontal part of the Cartesian plane that usually represents the independent variable.

A

X-axis

18
Q

It is the vertical part of the Cartesian plane that represents the dependent variable.

A

Y-axis

19
Q

It is a linear representation of the trend that the variables show.

A

Curve

20
Q

It is a trend line that lies exactly close to one of the axes, but never touches it.

A

Asymptote

21
Q

It is a singular point on a curve wherein a moving point starts to move backward.

A

Cusp

22
Q

It is a point in a curve wherein the curvature changes.

A

Inflection Point

23
Q

These are points with the largest and smallest values, respectively, along the curve.

A

Maximum and Minimum

24
Q

[Kinds of Variables]
It is a variable that is independent (variation does not depend on the outcome of the other) and explanatory (variable that influences the outcome of the other)

A

Plotted on the Abscissa

25
Q

[Kinds of Variables]
It is a variable that is dependent (variation changes accordingly as the value of the independent variable changes) and the response (variable that answers the question in the study, and is influenced by explanatory variables)

A

Plotted on the Ordinate

26
Q

[Kinds of Variables]
It is represented by various symbols on the same coordinate system.

A

Categorical

27
Q

These are hidden variables.

A

Lurking

28
Q

What are the 3 types of graphs?

A

time series, scatter plot, histogram

29
Q

[Types of graphs]
These are graphs used to represent changes in the y-axis as time passes (which is represented by the x-axis).

A

Time Series

30
Q

[Types of graphs]
These are graphs used to represent data variance and shows the relationship between one variable to another.

A

Scatter Plot

31
Q

[Types of graphs]
It is a graph used to represent the frequency of a given variable spread over certain intervals.

A

Histogram

32
Q

This refers to the degree of closeness and agreement between the acquired value and the true value.

A

Accuracy

33
Q

This refers to the degree of closeness of the results repeatedly gathered to the true value.

A

Precision

34
Q

It pertains to the errors in a given value.

A

Uncertainty

35
Q

Uncertainty happens due to:

A
  1. Limitations of the measuring device
  2. The skills of the one making the measurement
  3. Irregularities in the object
  4. Other situational factors
36
Q

These are uncertainties marked by having the smallest significant figure of the given value.

A

Absolute uncertainties

37
Q

These are simply uncertainty values divided by the given value.

A

Fractional uncertainties

38
Q

These are fractional uncertainties of a piece of data converted into percentile values.

A

Percentage uncertainties

39
Q

It refers to the miscalculation of data or a lapse of judgment during the experiment or research that yielded dubious results.

A

Error

40
Q

[Types of Errors]
These are errors due to variations in the environment and/or with measuring techniques.
* data values are scattered alongside the true value
* error values have varied magnitude and direction
* usually affects the reading of data

A

Random

41
Q

[Types of Errors]
These are errors caused by faulty devices and/or incorrect handling of such instruments.
* data values are deviating away from the true value
* error values have consistent magnitude and direction
* error occurs during data gathering

A

Systematic
