We would recommend using X-bar and R-charts to monitor the weight of the jars of pickles. The X-bar chart will show the average weight of the samples, while the R-chart will show the range of the samples. This combination of charts is appropriate for continuous data with sample sizes greater than 10, which is likely the case for weighing jars of pickles. P-charts and C-charts would not be appropriate in this context as they are used for monitoring proportions or counts, not continuous data.
