An SPC chart in Excel is a statistical process control tool used to monitor and analyze data to ensure a process is running within specified limits. It helps identify any variations in the process that could lead to defects or deviations from desired outcomes.

There are different types of SPC charts in Excel, each designed for a specific purpose. Some common types include: - X-bar and R charts: Used to monitor the central tendency (mean) and variation (range) of a process. - X-bar and S charts: Similar to X-bar and R charts, but with the standard deviation instead of the range. - Individual and Moving Range (ImR) charts: Useful for processes with short production runs or frequent changes. - p-charts: Used to monitor the proportion of nonconforming items in a sample. - c-charts: Used to monitor the number of defects per unit. - np-charts: Similar to p-charts, but used when the sample size remains constant.
