●● What is an indeterminate progress bar?
Answer: A progress bar that shows activity is happening but does not
indicate how much is complete or how long it will take. It is useful when
the duration or percentage cannot be accurately estimated.
●● What is a splash screen?
Answer: A full-screen graphic or image displayed while an application
or game is loading, often with branding or a loading animation. It
distracts the user and sets the tone.
●● What is console output used for in terms of progress indication?
Answer: Text-based feedback printed to the terminal or console, such as
log messages, percentage complete, or status updates. Common in
command-line tools and servers.
●● What is a skeleton screen?

loading by reserving space and structure.
,●● What is a throbber?
Answer: An animated icon (often a spinning wheel, pulsing dots, or
similar) that indicates ongoing activity without showing progress
percentage. Also known as a loading spinner.
●● What do the listed economic and social indicators try to measure?
Answer: They attempt to quantify different aspects of societal progress,
economic health, inequality, human well-being, and quality of life:
Gross Domestic Product, Gross National Income, Gini Coefficient,
Human Development Index, Multidimensional Poverty Index, Labor
Productivity, Happiness Index, Passport Index, Big Mac Index.
●● What does Gross Domestic Product (GDP) measure?
Answer: The total monetary value of all final goods and services
produced within a country's borders in a specific time period. It is the
most common measure of economic activity and size.
●● What does Gross National Income (GNI) measure?
Answer: The total income earned by a country's residents and
businesses, including income from abroad, minus income earned by
foreigners within the country. It focuses on who earns the income rather
than where it is produced.
●● What does the Gini Coefficient measure?
,Answer: The degree of inequality in the distribution of income or wealth
within a population. It ranges from 0 (perfect equality) to 1 (perfect
inequality). Higher values indicate greater inequality.
●● What does the Human Development Index (HDI) measure?
Answer: A composite statistic of life expectancy, education (mean and
expected years of schooling), and per capita income. It assesses overall
human development beyond just economic output.
●● What does the Multidimensional Poverty Index (MPI) measure?
Answer: Poverty across multiple dimensions including health, education,
and living standards (e.g., nutrition, child mortality, schooling,
sanitation, electricity access). It captures deprivations beyond income
alone.
●● What does Labor Productivity measure?
Answer: The amount of economic output (goods and services) produced
per unit of labor input (usually per hour worked or per worker). It
reflects efficiency of the workforce.
●● What does the Happiness Index (World Happiness Report) measure?
Answer: Subjective well-being based on surveys asking people to rate
their life satisfaction, along with factors like social support, freedom,
generosity, and perceptions of corruption.
, ●● What does the Passport Index (Henley Passport Index) measure?
Answer: The strength of a country's passport based on the number of
destinations its holders can access without a visa or with visa on arrival.
It reflects global mobility and diplomatic relations.
●● What does the Big Mac Index measure?
Answer: Purchasing power parity (PPP) by comparing the price of a Big
Mac burger across countries. It serves as a light-hearted way to assess
whether currencies are over- or undervalued relative to the US dollar.
●● What are the advantages and disadvantages of using GDP as a
measure of societal progress?
Answer: Advantages: Easy to calculate and compare, correlates with
many aspects of living standards. Disadvantages: Ignores income
distribution, non-market activities (e.g., household work), environmental
degradation, and does not measure well-being or happiness directly.
●● How accurately does GDP reflect what it is like to live in a country?
Answer: It reflects the size and activity of the economy well but poorly
reflects quality of life, inequality, environmental health, or personal
happiness. Many countries have high GDP but significant social or
environmental issues.

listed?
