I just did this for homework, advantages include creating a graph for not constant date like opinions such as black cats V.S white cats in your class, or a classroom based experiment, how many pennies a paper bridge of certain length can hold, different answers every time. ANSWERS WILL VARY for opinion based or experiment based data. Things that will graph at a constant rate is statistics or mathematical number sequences.

How can you model data with a linear equation?
by figuring out the equation
When does it make sense to chose a linear function to model a set of data?
If a linear model accurately reflects the measured data, then the linear model makes it easy to predict what outcomes will occur given any input within the range for which the model is valid. I chose the word valid, because many physical occurences may only be linear within a certain range. Consider applying force to stretch a spring. Within a certain distance, the spring will move a linear distance proportional to the force applied. Outside that range, the relationship is no longer linear, so we restrict our model to the range where it does work.
What is linear interpolation used for?
Linear interpolation is used as a method used in mathematics of constructing a curve that has the best fit to a series of points of data using linear polynomials.
How are gaps in a sequence filled in?
What you are asking is not precisely clear, but in general missing data is filled in by a process of interpolation. eg. Linear interpolation is a method of curve fitting using linear polynomials to construct new data points within the range of a discrete set of known data points.
What is the Advantages of scatter diagram?
It allows a quick look at the data to establish whether or not there is any relationship between the variables and also an indication of the nature of the relationship: linear, quadratic, power etc.

Advantages of flat data model?
two main early navigational data models were the hierarchical model and the CODASYL model (network model)
what are the advantages of using a grouped data over an ungrouped data?
Nothing, they stealing yo data
What is the normal probability plot of residuals?
When you use linear regression to model the data, there will typically be some amount of error between the predicted value as calculated from your model, and each data point. These differences are called "residuals". If those residuals appear to be essentially random noise (i.e. they resemble a normal (a.k.a. "Gaussian") distribution), then that offers support that your linear model is a good one for the data. However, if your errors are not normally distributed, then they are likely correlated in some way which indicates that your model is not adequately taking into consideration some factor in your data. It could mean that your data is non-linear and that linear regression is not the appropriate modeling technique.

What are the advantages of using a graph to display data?
It Is Easier To Read
What are the advantages of using checks?
they help keep records of data
What are the advantages of linear interpolation?
Advantages over what? For what? Generally linear interpolation is done because one infers that the relationship between points is linear and/or it is the the easiest kind of interpolation. In the absence of data or theory to help you infer the relationship between points the principle of parsimony suggest that use the simplest that gets the job done - linear.

What are the advantages and disadvantages of network data model?
Network data model is just like a normal database model. In network model the data is seen as related to each other by links. Or we can say the relation between the data is represented by links.
What are the advantages and disadvantages of a hierarchical data model and network data model?
Hierarchical data model :Advantages- simplicity- data security- data integrity- efficiency- ease to add and delete recordDisadvantages- implement complexity- database management problem- lack of structural independence- programming complexity- implementation limitation- procedural access languageNetwork data model :Advantages- easy to access data- can handle more relationship types- data independence- data integrity- data independenceDisadvantages- system complexity- lack of structural independence- procedural access language
