Inorganic qualitative analysis generally refers to a systematic scheme to confirm the presence of certain, usually aqueous, ions or elements by performing a series of reactions that eliminate ranges of possibilities and then confirms suspected ions with a confirming test.

Many researchers combine qualitative and quantitative forms of analysis to better answer questions which cannot be studied in laboratory settings, particularly in the social sciences and in education.

Data analysis encompasses methods for processing both quantitive ( numerical ) and qualitative ( non-numerical ) research data.

One of the most commonly used methods for qualitative research in educational psychology is protocol analysis.

The assessment may use a subjective qualitative analysis based on informed opinion, or where reliable dollar figures and historical information is available, the analysis may use quantitative analysis.

Use qualitative analysis or quantitative analysis.

Neutron activation analysis is a sensitive multi-element analytical technique used for both qualitative and quantitative analysis of major, minor, trace and rare elements.

As such, it is similar to the social sciences in using qualitative research and intersubjectivity as tools to apply measurement and critical analysis.

This objective investigation may include the use of both quantitative methods ( surveys, polls, demographic and census analysis ) and qualitative approaches such as participant observation, interviewing, and analysis of archival, historical and documentary materials.

He also studied qualitative analysis, and conducted chemical experiments on the train until an accident prohibited further work of the kind.

* Coding ( social sciences ), refers to an analytical process in which data, in both quantitative form ( such as questionnaires results ) or qualitative ( such as interview transcripts ) are categorised to facilitate analysis

There are numerous qualitative chemical tests, for example, the acid test for gold and the Kastle-Meyer test for the presence of blood.

This property is used to determine the presence of boron in qualitative analysis.

Although Luttinger liquids are physically the same as Fermi liquids, the restriction to one dimension gives rise to several qualitative differences such as the absence of a quasiparticle peak in the momentum dependent spectral function and the presence of spin density waves.

A better representation which can handle the large number of variables and parameters is called a bifurcation diagram ( Bifurcation theory ): the presence of these special steady-state points at certain values of a parameter ( e. g. mass ) is represented by a point and once the parameter passes a certain value, a qualitative change occurs, called a bifurcation, in which the nature of the space changes, with profound consequences for the protein concentrations: the cell cycle has phases ( partially corresponding to G1 and G2 ) in which mass, via a stable point, controls cyclin levels, and phases ( S and M phases ) in which the concentrations change independently, but once the phase has changed at a bifurcation event ( Cell cycle checkpoint ), the system cannot go back to the previous levels since at the current mass the vector field is profoundly different and the mass cannot be reversed back through the bifurcation event, making a checkpoint irreversible.

Urine is used for qualitative analysis as it cannot give any indication of impairment due to the fact that drug presence in urine only indicates prior exposure.

The inspection of the contents of the stomach must be part of every postmortem examination if possible because it may provide qualitative information concerning the nature of the last meal and the presence of abnormal constituents.

The Abelin reaction is a qualitative reaction for demonstrating the presence of arsphenamine and neoarsphenamine in blood and urine.

A bioindicator is an organism or biological response that reveals the presence of the pollutants by the occurrence of typical symptoms or measurable responses, and is therefore more qualitative.

From a qualitative standpoint, the path can be approximated by an arc of a circle for a limited time, and for the limited time a particular radius of curvature applies, the centrifugal and Euler forces can be analyzed on the basis of circular motion with that radius.

It is possible to obtain a qualitative understanding of many diffraction phenomena by considering how the relative phases of the individual secondary wave sources vary, and in particular, the conditions in which the phase difference equals half a cycle in which case waves will cancel one another out.

Although the concept of population is central to ecology, evolutionary biology and conservation biology, most definitions of population rely on qualitative descriptions such as " a group of organisms of the same species occupying a particular space at a particular time " Waples and Gaggiotti identify two broad types of definitions for populations ; those that fall into an ecological paradigm, and those that fall into an evolutionary paradigm.

The division of focus and methodologies has produced several subfields, in particular: general positive psychology, focusing primarily on the study of psychological phenomenon and effects ; and personal effectiveness, focusing primarily on analysis, design and implementation of qualitative personal growth.

Alfred Russel Wallace believed qualitative novelties could arise through the process of spiritual evolution, in particular the phenomena of life and mind, Wallace attributed these novelties to a supernatural agency.

For example, the research findings of a qualitative case study of primary school children in a particular school and their mobile phone use will tell us more about the mobile phone of children in the general population, than of adults.

In particular, qualitative methods are widely used as exploratory methods ; the results of qualitative analysis are used to design quantitative research which tests null hypotheses derived from the qualitative observations.

In educational psychology, qualitative research is used to address questions concerned with developing an understanding of the meaning and collecting nonnumerical relevant data to gain insights into particular phenomenon.

Furthermore, qualitative data can be used to strengthen quantitative research designs in general and intervention research designs ( i. e., experimental, quasi-experimental ) in particular.

In the conventional view, qualitative methods produce information only on the particular cases studied, and any more general conclusions are only propositions ( informed assertions ).

This view has been disputed by Oxford University professor Bent Flyvbjerg, who argues that qualitative methods and case study research may be used both for hypotheses-testing and for generalizing beyond the particular cases studied.

In particular, the qualitative behavior of the system depends crucially on whether the quadratic equation for γ has one real solution, two real solutions, or two complex conjugate solutions.

The biologist and spiritualist Alfred Russel Wallace ( 1823 – 1913 ) believed that qualitative novelties could arise through the process of spiritual evolution, in particular the phenomena of life and mind, Wallace attributed these novelties to a supernatural agency.

Locational predicates, like grue, cannot be assessed without knowing the spatial or temporal relation of x to a particular time, place or event, in this case whether x is being observed before or after time t. Although green can be given a definition in terms of the locational predicates grue and bleen, this is irrelevant to the fact that green meets the criterion for being a qualitative predicate whereas grue is merely locational.

As a discipline, cultural analysis is based on using qualitative research methods of the social sciences, in particular ethnography and anthropology, to collect data on cultural phenomena ; in an effort to gain new knowledge or understanding through analysis of that data.

In particular, the comparative method is generally used when neither the experimental nor the statistical method can be employed: on the one hand, experiments can only rarely be conducted in political science ; on the other hand the statistical method implies the mathematical manipulation of quantitative data about a large number of cases, while sometimes political research must be conducted by analyzing the behavior of qualitative variables in a small number of cases.
