Global temperature changes over the past 135 years. There has been a lot of discussion
regarding changing weather patterns and a possible link to pollution and greenhouse gasses.

Grouping data
One of the first steps to processing a large set of raw data is to arrange the data values together into a smaller number of groups, and then count how many of each data value there are in each group. The groups are usually based on some sort of interval of data values, so data values that fall into a specific interval, would be grouped together. The grouped data is often presented graphically or in a frequency table. (Frequency means “how many times”)
Group the elements of
Data Set 1 to determine how many times the coin landed heads-up and how many times the coin landed tails-up.
There are two unique data values: H and T. Therefore there are two groups, one for the H-data values and one for the T-data values.

There are 100 data values and the total of the frequency column is 44+56=100.
In economics, a perfect market refers to a theoretical construct where all participants have perfect information, goods are homogenous, there are no barriers to entry or exit, and prices are determined solely by supply and demand. It's an idealized model used for analysis,

Quantity demanded refers to the specific amount of a good or service that consumers are willing and able to purchase at a give price and within a specific time period. Demand, on the other hand, is a broader concept that encompasses the entire relationship between price and quantity demanded

Economic growth as an increase in the production and consumption of goods and services within an economy.but
Economic development as a broader concept that encompasses not only economic growth but also social & human well being.

What do you think is more important to focus on when considering inequality ?
sir...I just want to ask one question... Define the term contract curve? if you are free please help me to find this answer 🙏

it is a curve that we get after connecting the pareto optimal combinations of two consumers after their mutually beneficial trade offs

thank you so much 👍 sir

In economics, the contract curve refers to the set of points in an Edgeworth box diagram where both parties involved in a trade cannot be made better off without making one of them worse off. It represents the Pareto efficient allocations of goods between two individuals or entities, where neither p
