• 1. Entry Activity – Calculate the mean from the frequency table below Height Frequency (cm)0 ≤ h < 10 510 ≤ h < 20 620 ≤ h < 30 1030 ≤ h < 40 2 ∑
• 2. Entry Activity – Calculate the mean from the frequency table below Height Frequency Mid-point F x MP (cm)0 ≤ h < 10 5 5 2510 ≤ h < 20 6 15 9020 ≤ h < 30 10 25 25030 ≤ h < 40 2 35 70 ∑ 23 435 ∑ (Frequency x Mid-point) ÷ ∑frequency = 435 ÷23 = 18.913034 = 18.9 to 1 d.p.
• 3. Today I will learn to calculate the standard deviation from a: set of data frequency table grouped frequency tableKey WordsMeanStandard deviationDifference
