Difference between discrete and continuous?
A continuous variable is one that can take any value within an interval (or a set of intervals). A discrete variable is one that can only take certain values.Some further notes:* Often a discrete variable takes integer values, but that is not necessary.* Neither discrete nor continuous variables need be limited to a finite number of possible values.* Frequently, continuous variables are continuous only in principle, and the measuring instruments or recording make them discrete. Eg your height is continuous but as soon as it is recorded as 1.75 cm or 5'9", it is made discrete.
What is correlation ratio?
The correlation ratio, often denoted as η (eta), measures the strength and direction of association between a continuous variable and a categorical variable. It quantifies how much variability in the continuous variable can be explained by the categorical variable. Unlike Pearson's correlation, which is limited to linear relationships between two continuous variables, the correlation ratio can capture relationships involving categorical data. It is particularly useful in statistical analysis to understand the influence of categorical factors on continuous outcomes.
What graph has finite data?
A graph with finite data is one that represents a limited number of discrete points or values. For example, a bar graph illustrating the number of students in different classes at a school is finite, as it only includes specific, countable data points. Similarly, a scatter plot showing the relationship between two variables collected from a survey of a fixed number of respondents is also finite. In contrast, a continuous graph, like a sine wave, represents an infinite set of data points.
What are the disadvantages of scatter diagram?
Scatter diagrams can be limited by their inability to establish causation, as correlation does not imply causation. They can also become cluttered and difficult to interpret when dealing with large datasets or multiple variables, which may obscure meaningful insights. Additionally, scatter diagrams are primarily useful for visualizing relationships between two continuous variables, making them less effective for categorical data or complex interactions. Lastly, they may not provide sufficient information about the underlying data distribution, potentially leading to misinterpretations.
How many variables can be accepted by one scanf() statement?
The scanf() function in C can accept multiple variables as input, with the number limited only by the available system resources and the specific format string used. Each variable must correspond to a specific format specifier in the format string, and the total number of variables is typically constrained by readability and manageability of the code. In practice, it's common to see scanf() handling anywhere from one to several variables at a time, but it can technically handle dozens if needed. However, for clarity and ease of maintenance, it's advisable to keep the number of variables reasonable.

Is absorbance considered a continuous variable?
Yes, absorbance is considered a continuous variable because it can take on any value within a range, rather than being limited to specific discrete values.
Can continuous variables be negative?
Yes, continuous variables can be negative. For example, we generally treat temperature in as a continuous variable and temperature in the Fahrenheit or Celsius scales can have negative values. Considerably more explanation is below.Conventionally, there are three types of variables, which can go by names other than the ones I list:CategoricalDiscreteContinuousCategorical variables (which can be further sub-classified) are variables that aren't numeric in nature. So if you record the colors of a traffic light or the gender of a study subject, those are categorical in nature.Discrete variables are those that are numeric in nature, but which have a limited resolution with which we can measure them. Common examples are counts, which can only be integers, never decimals. So if you record the number of unfilled soda cans that come out of a filling machine, you are getting discrete data.Continuous variables can theoretically be measured with infinite precision. To be very technical, it's almost impossible to record continuous data because you'd have to be able to record an infinite number of decimal points, but in practice we can treat many different kinds of data as continuous. For example, US Dollars are conventionally only measured to two decimal points, but we can usually treat them as continuous. It turns out that for practical purposes, the key to treating data as continuous is to not have repeated values. Even count data, which are discrete by definition, can be treated as continuous in many circumstances. Look in a statistics reference for information about the normal approximation to the binomial distribution or the normal approximation to the Poisson distribution for more information.
What Would be the Advantage Of Continuous Wave Doppler Over pulsed Doppler?
Continuous wave Doppler allows for measurement of high velocities because it does not have a limit on the range of velocities it can detect compared to pulsed Doppler which has a limited range. Continuous wave Doppler is also able to detect continuous flow patterns whereas pulsed Doppler can only sample at specific points.
What are the strengths and weaknesses of correlational methods of psychology?
The strengths of correlation methods is that it allows researchers to examine relationships between two variables. The disadvantage is that it is not valid to assume that the relationship between two variables will apply to all similar variables in general.

What is the difference between limited and general direction?
What is the difference between limited and general direction?What is the difference between limited and general direction?My best guess would be in not knowing the full context in which you are asking this question. Limited would be in the context of a specific subject and therefor limited in nature. Whereas general would be more global in specifically addressing a broad range of subjects.Peace & blessings

What is the difference between finite and continuous cell lines?
Finite cell lines have a limited lifespan and eventually stop dividing, while continuous cell lines are immortal and can divide indefinitely. Continuous cell lines are derived from cancer cells or genetically modified to overcome cellular senescence.
What is local in computer scince?
In computer science, "local" typically refers to data or variables that exist and are accessible within a specific scope or context, such as within a function or a block of code. Local variables are usually declared and used within a limited area of a program, and their scope is restricted to that particular area.
