Graphical Presentation of Data

To make a graph effective, certain considerations must be observed, includings

• Choosing the coordinate scales

• Labelling the curves

• Labelling the plotting data

• Preparing the title properly

A line of best fit should show the overall trend of the data. The line does not have to go through all of the data point

• True

• False

• Not Sure

What is the function of mathematical model?

• Describe the relationship between the variables and its uncertainties

• Describe the relationship between the variables in an experiment

• Describe the relationship between the variables and the behaviors of system

• Describe the relationship between the variables and the line of best fit

A test plot is a graph made with mathematically manipulated data for the purpose of testing a mathematical relation

• True

• False

The mathematical model for the graph is S = 0.30 m

• True

• False

• Not sure

The basis mathematical model for inverse relation is

• y = mx + b

• y = ax^2 + bx + c

• ln⁡ y=bx + ln ⁡a

• y = ax^2

The process of linearising the side opening parabolas in Figure is known as

• Linear relation

• Squared relation

• Test plot

• Mathematical analysis

In engineering, the graph semi-log is plotted when

• The limit value of x is very small

• The data having a trend of exponential equation

• The limit value of y is very big

• The data having an equation or trend of power relation

Which graph shows a direct proportional graph?

• 
• 
• 
• 

What is the important element that is missing from the chart?

• Gridlines

• Line of best fit

• Legend

• Data labels
