Is a cross sectional study quantitative or qualitative study?
Cross-sectional study can be either qualitative or quantitative or mix method, Cross-sectional surveys are used to gather information on a population at a single point in time. An example of a cross sectional survey would be a questionaire that collects data on how parents feel about Internet filtering, as of March of 1999. A different cross-sectional survey questionnaire might try to determine the relationship between two factors, like religiousness of parents and views on Internet filtering.Takes place at a single point in timeDoes not involve manipulating variablesAllows researchers to look at numerous things at once (age, income, gender)Often used to look at the prevalence of something in a given population.Hassan Elkatawnehحسان القطاونه
A 600N clown on stilts says to two 600 N clowns sitting on the ground i am exerting twice as much pressure as you two together! is this true?
It is likely to be untrue: he is likely to be exerting far more pressure. It will be true if the cross sectional area of the bases of the stilts are a quarter of the cross-sectional area of the contact area between the sitting clowns and the ground. The stilts' base is likely to be much smaller.
How platinum is very pliable just one gram of it can be stretched into a wire of what length?
depends upon the thickness. I have heard of 1 mil diameter wire. Using this: density of Pt is 21.45  g/cm3 1g has a volume of 0.0466 cm3 volume is cross sectional area x length 1 mil is 0.00254 cm, radius is 0.00127, area is 5.067E-6 divide volume by cross sectional area to get length, L = 9,197 cm or 92 meters
Which cross sectional view correctly shows the general shape of the stream bottom between points a and b?
To accurately depict the stream bottom's shape between points a and b, one must consider factors such as the gradient of the stream, sediment deposition, and erosion patterns. Typically, a cross-sectional view would show a concave shape if the stream flows smoothly, reflecting a gradual slope. If there are areas of erosion or deposition, these would create variations in the cross-section. Therefore, the correct view would illustrate these features, showing a realistic representation of the stream's bottom profile.
What is CROSS sectional study retrospective study?
A cross-sectional study is a type of observational research that analyzes data collected from a population at a single point in time to assess relationships between variables. In contrast, a retrospective study looks at past data to investigate possible links between exposure and outcome variables.

Is CROSS sectional study a prospective study?
Basically it is not. However, there are studies being tiltled as prospective cross sectional study, but these kind fo terms should be used with caution and clear explanation.
What is a alternative to a cross sectional study?
A longitudinal study is an alternative to a cross-sectional study. In a longitudinal study, data is collected from the same subjects over a period of time, allowing researchers to observe changes within individuals. This type of study provides a more in-depth understanding of how variables evolve over time compared to cross-sectional studies.
What is the major difference between a longitudinal study and cross sectional study?
the cross-sectional study selects a sample that has all the age ranges the researchers are interested in verses one group that is followed throught time
Can cross-sectional study be classified into comparative or associative study?
Yes, cross-sectional studies can be classified as comparative or associative. Comparative cross-sectional studies involve comparing different groups at one point in time, while associative cross-sectional studies examine the relationship between variables within a single group at one point in time.
Does Cross-sectional study measure relationships between disease and other variables?
They can do.

Longitudinal study versus cross-sectional study?
A longitudinal study and a cross-sectional study are methods of collecting scientific data. A longitudinal study is the method that gathers data on a subject for a particular period of time and the subject's response to particular variables. A cross-sectional study is where more than one subject is used for the collection of data at different points in time in response to particular variables. These types of studies are sometimes used to determine correlation.
In a cross-sectional study individuals of what age groups are compared at one time?
different
