Step-by-step explanation:
When analyzing a market, economists deal with the problem of changing factors by using technical analysis, economic indicators, and other relevant factors. Technical analysis involves studying past market data such as price movements and trading volume to identify patterns and trends that can help predict future market behavior. Economic indicators, on the other hand, are statistics that provide information about various economic factors, such as inflation rates, employment levels, and consumer spending, which can influence market conditions.
