  1. When data is classified on the basis of single variable, the distribution is known as univariate frequency distribution.
  2. It aims to make description about the particular variable.
  3. It is also known as one-way frequency distribution.
  4. Ex : Height of students in a class.

Bivariate Frequency Distribution :

  1. When the data is classified on the basis of two variables, the distribution is known as bivariate frequency distribution.
  2. It aims to determine the empirical relationship between the two variables.
  3. It is also known as two-way frequency distribution.

Protozoa are small (but not simple) organisms. They are single-celled heterotrophic eukaryotes, which eat bacteria and other food sources. It is an old term, and the wider term protist is generally preferred today. 

These are divided into four major groups.

(1) Amoeboid protozoans or sarcodines. They are unicellular, jelly-like protozoa found in fresh or sea water and in moist soil. ...

(2) Flagellated protozoans or zooflagellates. ...

(3) Ciliated protozoans or ciliates. ...

(4) Sporozoans.

Polyunsaturated fats can help lower your LDL (bad) cholesterol. Cholesterol is a soft, waxy substance that can cause clogged or blocked arteries (blood vessels). Having low LDL cholesterol reduces your risk for heart disease.

Polyunsaturated fats include omega-3 and omega-6 fats. These are essential fatty acids that the body needs for brain function and cell growth. Our bodies DO NOT make essential fatty acids, so you can only get them from food.

Omega-3 fatty acids are good for your heart in several ways. They help:

  • Reduce triglycerides, a type of fat in your blood
  • Reduce the risk of developing an irregulat heartbeat (arrhythmia).
  • Slow the buildup of plaque in your arteries
  • Slightly lower your blood pressure

Commercial banks are financial institutions that accept deposits from their customers, then use those deposits to make loans for individuals and businesses. In addition to these activities, commercial banks offer a wide variety of financial services, including checking accounts, credit and debit cards, and savings accounts. Commercial banks are owned by shareholders and function for the purpose of generating profits. Examples of commercial banks include Bank of America, JP Morgan Chase and Wells Fargo. Objectives of Commercial Banks The objectives of commercial banks are two-fold; to offer a wide variety of services to individual and business customers, and to collect payments including fees, charges and interest on the products and services provided to customers for the purpose of generating profits for shareholders. Commercial banks typically offer a robust suite of services in an attempt to be able to serve all the financial needs of each customer. This results in the opportunity to maximize revenues from each customer. For example, a customer who has checking and saving accounts, loans, and credit cards for personal and business use at one bank generates revenues through numerous channels. Revenues can be increased further if the customer also buys stocks and bonds through a bank’s brokerage arm. The Importance of Commercial Banks Commercial banks play a critical role in the country’s financial system by providing liquidity through the creation of loans, access to money on deposit and the availability of revolving debt using credit cards. Access to money enables businesses to grow, consumers to make purchases of goods and services, and jobs to be created. This liquidity, combined with the expedited, simple and efficient transfer of money for a wide range of financial transactions, is an essential factor in a healthy economy.
