Error analysis(Johnson Noise)  Our The discrepancy between our  resultfor the Boltzmann constant  ($1.46 \times 10^-23 \text{m2 kg s-2 K-1}$) is approximately 5.8\% higher than and  the accepted value Boltzmann constant  ($1.38 \times 10^-23 \text{m2 kg s-2 K-1}$).Both K-1}$)is approximately 5.8\% . Both  sets of data we obtained (with a $1K\Omega$ resister and a $10K\Omega$) gave a consistent value for the Boltzmann constant, constant which is a matter of accuracy rather than precision,  so this error is most likely a systematicerror rather than a random  error. T? Assuming that our thermometer is accurate (for room temperature), the temperature within the instrument, where the resister is, may be higher. As we can see in Eq.~ \ref{eq:boltzmann}, with a higher T, we would have a lower K_B value which is opposite to what our value is, so this is unlikely what is causing the error.
