Statistical package used: R
Task: interaction plot with error bars for treated and untreated Samples

Interpretation:

The figure presents the mean Vitamin C concentration under five storage methods, comparing treated and untreated samples. The error bars indicate the variability/uncertainty around the mean values.
Te results show that Vitamin C concentration varied considerably with storage method and treatment status, with a noticeable crossover pattern between the two treatment lines. This pattern suggests a possible interaction between storage method and treatment status, although statistical analysis (two-way ANOVA) is required to establish whether the interaction is statistically significant.
