What graphs are used for categorical data?
The graph that is most used for categorical data is the pie chart. Bar graphs have also been used for categorical data.
What term do demographers use to refer to the number of children an average woman has?
Demographers use the term "total fertility rate" (TFR) to refer to the average number of children a woman is expected to have during her lifetime, based on current age-specific fertility rates. The TFR is a key indicator used to analyze population growth and reproductive behavior in different regions. It helps inform policies related to family planning, healthcare, and social services.
What graph is most commonly used to show discrete data?
A bar graph works well in this case
What central tendency can be used on ordinal data?
For ordinal data, the median is the most appropriate measure of central tendency, as it effectively represents the middle value in a ranked order. While the mode can also be used to indicate the most frequently occurring category, the median provides a better summary of the data's central point, especially when the data is not symmetrically distributed. The mean is generally not suitable for ordinal data due to the lack of equal intervals between ranks.
What medium is used to convey data symbols?
Data source is used to convey data symbols.
Most data used by demographers comes from?
censuses
What is most data used by demographers comes from?
Most data used by demographers comes from national censuses, which provide comprehensive population statistics, including age, gender, ethnicity, and household composition. Additionally, vital statistics—such as birth and death records—along with surveys and administrative data from government agencies contribute valuable information. These sources enable demographers to analyze population trends, migration patterns, and demographic changes over time.
What is the demographers push and pull theory used to explain?
The push and pull theory is used by demographers to explain migration patterns. "Push" factors are conditions in a person's current location that make them want to leave, while "pull" factors are conditions in a potential destination that attract them to move there. By studying these factors, demographers can understand why people migrate and how migration trends develop.
What is the key measurement used by demographers to predict human population change?
Total fertility rate
How do you Speed Up Response Time through data Archiving?
Database archiving is a proven strategy that will archive rarely used data and provide easy access to data on demand. Basically, data is most valuable when it is created. As data ages, its relative value comes down. Such data can be archived to improve real time transactions.

The graph that is most used for categorical data is the pie chart. Bar graphs have also been used for categorical data.

Data modeling in system analysis and design?
data modelling is used for organising and structuring of data. we can get overview through generic modelling. organising of data means representing the data in such a way that it comes in a particular order via graphical representation.
What data structure and logarithm?
data structure is a way of storing data in a computer so that it can be used efficientlyan algorithm is a sequence of instructions, often used for calculation and data processing.Often a carefully chosen data structure will allow the most efficient algorithm to be used.
