Moreover, collecting the data of 8-10 people and analyzing it is a very easy task, it is easy to understand the pattern of their behaviors perhaps no statistics is required for this purpose but manually analyzing the collected data of dozens of people is near to impossible and will create lots of difficulties, therefor with the dataset of large groups we require to process the research with the help of statistics for example we need to find out whether the weight of people in Pakistan has the relationship with what they mostly eat. Here we have a large data sample from different parts of Pakistan and of different genders of different age groups, now we require to perform research with the help of statistics because we cannot find a trend or research just by observing the trend of data we collected.

Collection of the data through the answers of the questionnaire filled by the targeted sample based on the research topic and hypothesis. The data that is to be collected should be of the exact targeted sample or this may create errors in the research and can results in wrong or errors in the outcomes of the research.

statistics allows psychologists to present data is easier way to understand,=. Visual displays like tables, graphs, diagrams, frequency distribution tables’ helps psychologists to represent huge data and to create better understanding.

- Describing data:

Description provide a way to look over what already exists in a given population, like how many men and women are there, how many children are there or how many people are currently employed or unemployed.

- Make inference based upon data:

researchers can interpret things about a given sample or population. Psychologists use the data they have collected to test their research hypothesis and predict that what can happen.

PSYCHOLOGICAL RESEARCH:

Psychological research starts with an idea, but the idea must is followed by a research design, data collection, and data analysis, along with the interpretation of any findings.

Psychologist use two types of statistics:

2- Inferential statistics

1- Descriptive Statistics: in this psychologists give general pictures of scores or data this include central tendency, which involves mean, median, mode and variability which involve standard deviations that shows how far the results are away from average.

2- Inferential Statistics: in this psychologists draw conclusions from the data obtained from research. The widely used statistics if t-test that shows the differences in averages across groups are due to the effects of an independent variable.

If there was no statistics in psychology than it would have been difficult for us to drive and analyze results and check the validity. A correct methodology and study assure the data we have obtained our research, this will be useful if to be applied to real situations. By the statistical researches we can get off our minds from the myths and false perceptions and opinions about different psychological aspects. Statistics helps in making better and realistic judgments that may affect your health and wellbeing.
