What factor of a measurement tool determines the significant figures of a measured value? -The difference between 1.05 and 1.050 is that 1.050 is more accurate. It shows that the measurement has been taken from the thousandth decimal place and therefore the most precise.

Record the number of measurements (n) and calculate the sample mean (μ). ... Take the square root of the number you got in step 4. This is known as the standard deviation (σ). Finally, divide the standard deviation from step 5 by the square root of the number of measurements (n) to get the standard error of your estimate.

If you look at a ruler, one side uses the standard system and one uses the metric system. If you want to use inches, you need to look for the label 'inches,' 'inch' or 'in. ' Next you need to align the object you want to measure on the left side of the ruler, and then count how many inches it is.

mx and my are the means of x and y variables. the p-value (significance level) of the correlation can be determined : by using the correlation coefficient table for the degrees of freedom : df=n−2. or by calculating the t value : t=r√1−r2√n−2.

For a decimal number that is less than 1, all figures are significant except the leading zeros after its decimal point. For example 0. 235kg is less than 1 and has 3 sig. figs.

The number 0 has one significant figure. Therefore, any zeros after the decimal point are also significant. Example: 0.00 has three significant figures. Any numbers in scientific notation are considered significant.

Write down the “Asym. Sign” number for the Pearson Chi-square. If your “Asym. Sig.” number is less than 0.05, the relationship between the two variables in your data set is statistically significant.
