In general, statistics is a study of data: **describing properties of the data, which is called descriptive statistics, and drawing conclusions about a population of interest from information extracted from a sample, which is called inferential statistics**.

**Types of Statistics :**

- Descriptive Statistics : Descriptive statistics uses data that provides a description of the population either through numerical calculation or graph or table.
- Inferential Statistics :

- Step 1: Write your hypotheses and plan your research design.
- Step 2: Collect data from a sample.
- Step 3: Summarize your data with descriptive statistics.
- Step 4: Test hypotheses or make estimates with inferential statistics.
- Step 5: Interpret your results.

There are two kinds of Statistics, which are **descriptive Statistics and inferential Statistics**. In descriptive Statistics, the Data or Collection Data are described in a summarized way, whereas in inferential Statistics, we make use of it in order to explain the descriptive kind. Both of them are used on a large scale.

Generally, a statistic is used to estimate the value of a population parameter. For instance, suppose we selected a random sample of 100 students from a school with 1000 students. **The average height of the sampled students** would be an example of a statistic. So would the average grade point average.

This is the most common type of t test you'll come across in elementary statistics. You can test the mean of a single group against a known mean. For example, **the average IQ is 100**. You can test a class of children with a mean score of 90 to see if that's significant, or if it just happened by chance.

Statistics is **the science concerned with developing and studying methods for collecting, analyzing, interpreting and presenting empirical data**.

In general, statistics is a study of data: **describing properties of the data, which is called descriptive statistics, and drawing conclusions about a population of interest from information extracted from a sample, which is called inferential statistics**.

**A parameter is a number describing a whole population (e.g., population mean), while a statistic is a number describing a sample (e.g., sample mean)**. The goal of quantitative research is to understand characteristics of populations by finding parameters.

Inferential statistics have two main uses: making estimates about populations (for example, **the mean SAT score of all 11th graders in the US**). testing hypotheses to draw conclusions about populations (for example, the relationship between SAT scores and family income).

**Hormones produced by the pituitary gland**

- Adrenocorticotrophic hormone (ACTH)
- Thyroid-stimulating hormone (TSH)
- Luteinising hormone (LH)
- Follicle-stimulating hormone (FSH)
- Prolactin (PRL)
- Growth hormone (GH)
- Melanocyte-stimulating hormone (MSH)

**The biology major is much harder than Nursing**, due to the depth and complexity of learning. Nursing is also challenging and vast, however not as intense as Biology. It does, however, depend on your interests or passion for any profession, and another essential factor is your circumstances.

**Note Making Format**

- Heading/Title– This is the starting section of your note which must convey the central idea of the passage.
- Subheadings, Points, and Sub-points– Sub-headings are fundamental components of passage which further contain important information that needs to be delineated into points and subpoints.

To calculate depreciation using the straight-line method, **subtract the asset's salvage value (what you expect it to be worth at the end of its useful life) from its cost**. The result is the depreciable basis or the amount that can be depreciated. Divide this amount by the number of years in the asset's useful lifespan.

The Nobel Prize is an annual award for outstanding contributions to **chemistry, physics, physiology and medicine, literature, economics, and peace**, and is widely regarded as the most prestigious award one can receive in those fields.

**Coal-fired power plants burn coal to make steam and the steam turns turbines (machines for generating rotary mechanical power) to generate electricity**. Many industries and businesses have their own power plants, and some use coal to generate electricity for their own use and mostly in combined heat and power plants.

This year, among the top 10 rank holders, rank one **Subham Kumar** has been awarded the lowest mark in the interview. Kumar comes from Kushwaha community of Bihar, which is enlisted in the OBC category. But the final list of the selected candidates does not mention the category.

**Three functions of statistics are:**

- (1) Statistics helps in providing a better understanding and accurate description of nature's phenomena.
- (2) Statistics helps in the proper and efficient planning of a statistical inquiry in any field of study.
- (3) Statistics helps in collecting appropriate quantitative data.

The value of E **indicates the willingness of a half-cell to be reduced** (i.e. it is a reduction potential). It shows the how many volts are required to make the system undergo the specified reduction, compared to a standard hydrogen half-cell, whose standard electrode potential is defined as 0.00 V.

**Different Parts of an Electric Motor and Their Function**

- A power supply – mostly DC for a simple motor.
- Field Magnet – could be a permanent magnet or an electromagnet.
- An Armature or rotor.
- Commutator.
- Brushes.
- Axle.
