Census

Introduction

The census is a process of methodically calculating, gathering, and recording data on a certain population. It is mostly utilized while gathering information on the country's population, housing censuses, and agricultural, business, and supply needs.

In this tutorial, we will discuss census, categorical variables, and numerical data.

Definition

A census is, by definition, the process of carefully computing, compiling, and documenting information on a certain population. It is primarily used to gather data on the population, housing, agricultural, commercial, and supply demands of the nation. This information provided comprehensive details about the occupation, age factors, socioeconomic features, population size, and educational background of the population being surveyed. Both mathematics and statistics employ census to gather information on people's backgrounds, residences, and other characteristics.

Types

The methods used to gather and evaluate census data are numerous. The following phases describe how the practice operates: There are four crucial procedures to carry out in order to conduct a thorough survey:

By creating questions:

In order to gather accurate information from the population during the census, several questions should be developed, such as how many people live in each household, what their favourite products are, what their qualifications are, etc.

By asking questions:

In the appropriate way, pose the prepared questions. Ask a variety of questions in a random fashion. You must also pick the appropriate population subset from which to pose the questions. You can utilize sampling for selection, which entails using a certain subset and extrapolating the results to a larger population.

Tally the Results:

Tally will handle all the administrative and technical tasks and create several categories based on the interests of various people. You can employ basic tally markings.

Results Presentation:

The presentation may take any shape, including graphical or tabular formats. Even statistics can be used to display results. Bar graphs, pie charts, bar lines, and many more types of graphs are included in the graphical representation.

Central Tendencies

The central tendency of a data set can be determined using three essential indicators: Mean, Median, and Mode.

• The mean or arithmetic average are other names for the arithmetic mean. It is determined by adding up each number in a particular data set, then dividing the result by the overall number of items in the data set.

• Any group's median is the value that falls in the middle. At this stage, half of the data are more, and half are less.

The middle data point reflects the median of the data after the data are organised in ascending or descending order for the purpose of calculating the median.

• The mode gives us a general understanding of which elements in a data set have a tendency to recur most frequently.

Solved Examples

1) From January through June 30, 2010, hospitals had 150 beds available for both adults and children. The hospital's bed count rose to 200 on July 1 and stayed at that level through December 31. The hospital's adults and children received 27,813 patient days of care in the first six months. There were 35,873 days of service over the previous six months. What was the first six months' average daily census?

Answer − We must consider both leap and non-leap years when determining the average daily census. Let's compute for both of them.

27,813 patients in the first six months.

A non-leap year is −

The average Daily Census is calculated as the sum of all service days divided by all days = = 153.67

During a leap year: The average Daily Census is calculated as the sum of all service days divided by all days. = = 152.81

As a result, for the first six months, the daily average census became 153.67.

2) What types of questions ask during the collection of nominal data?

Answer − During nominal data collection general questions were asked like Name, gender, name of the school, etc.

3) What types of questions asks during the collection of ordinal data?

Answer − It is quantitative in nature, devoid of any descriptions in normal language, and used to calculate things like a person's height, age, IQ, etc.

4) What are the advantages of the census?

Answer − Advantages of the census are:

• For planning future development

• Calculation of population and housing characteristic levels and variations

• Calculating the labor force's sources

• Determining the position of women and their social and economic situation

• Employ for monetary benefit

5) Emily has three kids, whose combined ages are 36 and 16, respectively. The oldest child is the oldest, and the two younger children are the youngest. What is the combined age of the three kids?

Answer − Since we are aware that two of the children are young and one of the children is old, the result of their ages is 36. Thus, we discover the factors,

$\mathrm{36\:=\:2\times\:2\times\:3\times\:3}$

The total age equals 16.

The ages are so 12, 3, and 1.

Conclusion

A census is the gathering of information from the entire population, not just a few carefully chosen groups. The census count, which may also take place regularly, is the process of gathering this number and adding up the count. Data divided into categories are referred to as categorical data. Based on the qualitative characteristics of the collected raw data, groups are formed.

FAQs

1. What does census mean?

A census is a method used to gather information about the entire population. Another name for it is a comprehensive enumeration. A sample, on the other hand, is a portion of the population that represents the data for a chosen subset of the population.

2. What are statistics in a census?

A census is a survey that is carried out on the whole collection of observations that belong to the population in statistics. For instance, estimating the population, crop productivity, traffic on a specific road, etc.

3. What distinguishes sampling from a census?

While sampling only collects data on a portion of the population, a census collects information on every member of the population. While sampling limits the scope of the study to a single group, the census aids in more precise data analysis.

4. What does arithmetic mean?

The mean or arithmetic average are other names for the arithmetic mean. It is determined by adding up each number in a particular data set, then dividing the result by the overall number of items in the data set.

5. What do you mean by central tendency?

Central tendency measurements describe a data set by identifying the centre position in the data set as a single representative value. In general, the central tendency commonly used in statistics has three indicators: mean, median, and mode.
