What is the formula to calculate the kth quartile in the measures of position for grouped data?
What is the formula to calculate the kth quartile in the measures of position for grouped data?
- Qk = LB + [(kN/4) - cf]/f × i (correct)
- Qk = LB + [(kN/4) - cf]/(b × i)
- Qk = LB + [(kN/4) - cf]/(f × i)
- Qk = LB + [kN/4 - cf]/(f × i)
What is the formula to calculate the kth decile in the measures of position for grouped data?
What is the formula to calculate the kth decile in the measures of position for grouped data?
- Dk = LB + [(kN/10) - cf]/f × i
- Dk = LB + [(10kN/10) - cf]/f × i (correct)
- Dk = LB + [(10kN) - cf]/f × i
- Dk = LB + [(kN/10) - cf]/(f × i)
What is the formula to calculate the kth percentile in the measures of position for grouped data?
What is the formula to calculate the kth percentile in the measures of position for grouped data?
- Pk = LB + [(kN) - cf]/f × i
- Pk = LB + [(100kN) - cf]/f × i
- Pk = LB + [(kN/100) - cf]/(f × i)
- Pk = LB + [(kN/100) - cf]/f × i (correct)
