    97% of data should lie between two std. deviation around sample mean

    95% of data should lie between two two std. deviations around the sample mean

  1. According to the empirical rule, 95% of the data should lie within μ±2σ i.e. 2 standard deviations

  2. 2(34+13.5) = 95%

    95%

  3. 95%

    For a bell curve, The empirical rule tells you what percentage of your data falls within a certain number of standard deviations from the mean:
    • 68% of the data falls within one standard deviation of the mean.
    • 95% of the data falls within two standard deviations of the mean.
    • 99.7% of the data falls within three standard deviations of the mean.

  4. According to the empirical rule, 95% of the data should lie within μ±2σ i.e. 2 standard deviations

    1st SD = 34 + 34 = 68
    2nd SD = 13.5 + 13.5 = 27

    68 + 27 = 95

  5. 2(34+13.5) = 95%

  6. In particular, the empirical rule predicts that 68% of observations falls within the first standard deviation (µ ± σ), 95% within the first two standard deviations (µ ± 2σ), and 99.7% within the first three standard deviations (µ ± 3σ).

  7. According to the empirical rule, approximately 95 percent of the data should lie within μ±2σ.

  8. 95% of data lies between μ±2σ

  9. 95%

    68% — WIthin one standard deviation
    95% — Within Two Standard deviation
    99.7%- Within Three Standard Deviation

  10. According to the empirical rule, 95% of the data should lie within μ±2σ i.e. within 2 standard deviations of the sampling distribution of the sample mean

  11. 95% of data lies between μ±2σ

  12. 95%

    68% — WIthin one standard deviation ( μ±1σ)
    95% — Within Two Standard deviation ( μ±2σ)
    99.7%- Within Three Standard Deviation (μ±3σ)

  13. 95% of data lies between μ±2σ

  14. As per Bell curve, empirical rule says, 68% of data lie in μ±3σ range,
    95% of data lie in μ±2σ range, and 99.7% data lie in μ±σ range.
