How can I find f-value p-value nd alpha values?
I have natural fiber composites with lowered hardness but i am not able to distinguish hardness of particular specimen for example uf resin+ 12% untreated has no hardness instead uf+12% treated fiber gives 3 hardness....what does means.....i can't understand...
ASTM D 2583 is the standard test metod for the Barcol hardness test.
The method is similar to the test of Shore hardness: the hardness is based on indentation of a sharp point, but here you use a flat tip.
Barcol hardness is measured on a scale from 0 to 100B. A measurement of 60B is roughly equivalent to a Shore hardness of 80D.
Btw, you can watch this video to see the test: https://youtu.be/D-WGUD99WnY
The f-value, p-value, and alpha values are commonly used in statistical analysis to assess the significance of a hypothesis test. The f-value is a measure of the ratio of variability between groups to variability within groups. The p-value is a measure of the probability that the observed results occurred by chance, given that the null hypothesis is true. The alpha value is a pre-specified level of significance that is used to interpret the p-value.
To find these values, you will need to conduct a statistical analysis of your data. This can be done using a variety of statistical software programs or online tools. You will need to input your data and specify the appropriate statistical tests to calculate the f-value, p-value, and alpha values.
In regards to the hardness of the natural fiber composites that you mentioned, it is difficult to determine the meaning of these results without more information. It is possible that the treated fibers may have undergone some kind of chemical or physical modification that resulted in an increase in hardness, but more information about the treatment process and the properties of the fibers would be needed to confirm this.
