Understanding descriptive statistics is really important when making decisions based on data. It helps to summarize and understand big sets of information, making it easier for businesses to see overall trends quickly.
1. Measures of Central Tendency:
These are ways to find the center of a dataset.
Mean: This is the average value. It’s helpful when the data is normal. For example, if the average sales amount is $5000, it shows a basic level of performance.
Median: This is the middle value. It's important when there are outliers (values that are much higher or lower than the rest). If some sales are extremely high, the median gives a better idea of how most sales are doing.
Mode: This is the value that appears the most. It’s useful for managing stock because it helps identify the most popular products.
2. Measures of Variability:
These show how spread out the data is.
Variance: This shows how much the data varies. If response times have a high variance, it might mean the service is inconsistent.
Standard Deviation: This helps us understand how far the data points are from the mean (average). For example, if customer satisfaction scores have a low standard deviation, it means that customers have similar experiences.
By using these statistics, businesses can make smart decisions, improve their operations, and make customers happier!
