What number of statistics are false?
Our headline is (of course) made up. People say that numbers don't lie – but they can do if they are being used in the wrong way. Statistics are supposed to make something easier to understand, to help us grasp concepts, and to help wrap our heads around important topics.
By sheer chance alone, your sample contains sampling error that causes the statistics to be at least a little bit off. Your data are not 100% representative of the population because they are not the entire population! Samples can never provide a perfect depiction of the population from which it is drawn.
Are Statistics Reliable? 73.6% of statistics are false.
The data can be misleading due to the sampling method used to obtain data. For instance, the size and the type of sample used in any statistics play a significant role — many polls and questionnaires target certain audiences that provide specific answers, resulting in small and biased sample sizes.
The two types of statistics are: Descriptive and inferential.

Despite the objective and impartial appearance of statistics, it is a web of people and human processes that makes them trustworthy.
Statistical data will lend credibility to your research by providing facts and figures supporting your position. Therefore, statistics may be important to include in your class assignments, research papers, and theses.
The studies are often not repeatable and usually not predictive. The reason for this is that people and what they say or do are the bases of t he statistics. It seems axiomatic that people will perversely refuse to say or do the same thing twice running, or let anyone predict what they will do.

Can statistics be manipulated?
There are several undeniable truths about statistics: First and foremost, they can be manipulated, massaged and misstated.
Statistics deal with groups and aggregates only. 2) Statistical methods are best applicable to quantitative data. (3) Statistics cannot be applied to heterogeneous data. (4) If sufficient care is not exercised in collecting, analyzing and interpreting the data, statistical results might be misleading.
In 2007, toothpaste company Colgate ran an ad stating that 80% of dentists recommend their product. Based on the promotion, many shoppers assumed Colgate was the best choice for their dental health. But this wasn't necessarily true. In reality, this is a famous example of misleading statistics.
The statistical methods don't study the nature of phenomenon which cannot be expressed in quantitative terms. Such phenomena cannot be a part of the study of statistics. These include health, riches, intelligence etc. It needs conversion of qualitative data into quantitative data.
1. What is true about Statistics? Explanation: Statistics is used to process complex problems in the real world so that Data Scientists and Analysts can look for meaningful trends and changes in Data.
There are generally 3 kinds of averages commonly used in Statistics. They are: (i) Mean, (ii) Median, and (iii) Mode. Statistics is the study of Data Collection, Analysis, Interpretation, Presentation, and organizing in a specific way.
Statistics is the study and manipulation of data, including ways to gather, review, analyze, and draw conclusions from data. The two major areas of statistics are descriptive and inferential statistics.
Misleading statistics are created when a fault - deliberate or not - is present in one of the 3 key aspects of research: Collecting: Using small sample sizes that project big numbers but have little statistical significance. Organizing: Omitting findings that contradict the point the researcher is trying to prove.
Obvious lies are often caused by ignoring the characteristics of the sample distributions such as shape, symmetry and variability of the data. They can usually be avoided by plotting the data and using analytical tools to test the assumptions before selecting the correct methods.

The demerits of statistics is that it can prove anything. It can prove either side of the problem. Statistics is like a clay which can be moulded in any way so as to establish right or wrong conclusions.
Word forms: statistics
Statistics are facts which are obtained from analyzing information expressed in numbers, for example information about the number of times that something happens.
Quality in statistics means:
The data is still applicable. An appropriate method was chosen to collect the information. There is openness about anything that might influence interpretation. Care was taken to minimize any errors in both the collection process and the presentation of the data.
Statistical knowledge helps you use the proper methods to collect the data, employ the correct analyses, and effectively present the results. Statistics is a crucial process behind how we make discoveries in science, make decisions based on data, and make predictions.
Since number is included in the statistics, it becomes micro, its a sub set of statistics. So all numbers can be statistics but all figures cannot be statistics. Because various figures vary, and statistics are those which can be verified.
A statistic is a one-number description of a set of data, or numbers used as measurements or counts - lenghts of arms, number of days, number of fish in a catch - or, rarely, a number in that set.
Statistics are numerical statements of facts but all facts numerically stated are not statistics. The statement is true.

Statistics is the study and manipulation of data, including ways to gather, review, analyze, and draw conclusions from data. The two major areas of statistics are descriptive and inferential statistics.
Answer: All statistics are data, but all data are not statistics. This is because there can be two types of data - qualitative and quantitative. Statistics always deals with data, but only with quantitative data which includes figures and numbers.
A statistical question is a question that can be answered by collecting data that vary. For example, “How old am I?” is not a statistical question, but “How old are the students in my school?” is a statistical question.
1. What is true about Statistics? Explanation: Statistics is used to process complex problems in the real world so that Data Scientists and Analysts can look for meaningful trends and changes in Data.
A sample statistic (or just statistic) is defined as any number computed from your sample data. Examples include the sample average, median, sample standard deviation, and percentiles. A statistic is a random variable because it is based on data obtained by random sampling, which is a random experiment.

(1) Statistics laws are true on average. Statistics are aggregates of facts, so a single observation is not a statistic. Statistics deal with groups and aggregates only. 2) Statistical methods are best applicable to quantitative data. (3) Statistics cannot be applied to heterogeneous data.
- Statistics are numerically expressed.
- It has an aggregate of facts.
- Data are collected in systematic order.
- It should be comparable to each other.
- Data are collected for a planned purpose.
Bowley defined statistics as "Statistics is numerical statement of facts in any development of enquiry placed in relation to each other".
What percentage is statistically significant?
Statistical hypothesis testing is used to determine whether the result of a data set is statistically significant. Generally, a p-value of 5% or lower is considered statistically significant.
A simple idea that helps explain a lot of disagreements is that there's a difference between a statistic and a fact, and it's really hard to tell the two apart. A statistic is just a number. And numbers are as easily manipulatable, incomplete, and misleading as words are.
Statistics stands out as being the more difficult type of math mostly because of the abstract concepts and ideas that you will get to later on in your study.
