Analysis: The basic content of statistical analysis in preschool education research is divided into three main parts: descriptive statistics, inferential statistics and experimental design.

(1) Descriptive statistics mainly studies how to sort out, classify and simplify a large number of data obtained from experiments or investigations, and describe the whole picture of the data to show the nature of the research object.

(2) inferential statistic mainly studies how to infer the overall situation by using local (sample) data information.

(3) Before designing the experiment, we should strictly design the research steps, the sampling methods of subjects, the determination of sample size, the control of experimental conditions, and the selection of statistical analysis methods of results. The purpose of experimental design is to enable researchers to carry out experiments scientifically, economically and effectively.
