Hey, does anyone know how many observation is needed before we can prove that a trend is significance?

Ok, thanks for your help anyways, aye? I might need to talk to my supervisor about it.
The purpose of finding a trend in STAT (statistical analysis) is to identify patterns and relationships in data. The number of observations needed will depend on the complexity of the data and the level of confidence desired.
The appropriate number of observations needed can be determined by considering the type of data being analyzed, the research question being asked, and the level of confidence desired. Statistical methods such as power analysis can also be used to determine the minimum sample size needed for a given level of significance.
Having a sufficient number of observations is important because it increases the reliability and validity of the statistical analysis. With a larger sample size, the results are more likely to accurately reflect the population from which the data was collected.
Yes, it is possible to find a trend with a small number of observations. However, the results may not be as reliable and may not accurately represent the population. It is generally recommended to have a larger sample size for more accurate results.
Yes, there can be limitations to finding a trend with a large number of observations. If the data is too complex or the trend is too subtle, a large sample size may not be helpful. In some cases, a smaller sample size may be more appropriate for identifying specific trends or patterns.
