17The relationship of central tendency measures in skewed to
the left distribution is
- Aa Mean > Median>Mode
- Bb Mean < Median>Mode
- Cc Mean < Median<Mode
- Dd Mean = Median=Mode

- Cc Mean < Median<Mode
- Dd Mean = Median=Mode
- Ee Mean > Median=Mod
19 The relationship of central tendency measurements in normal
distribution is- Aa Mean > Median>Mode
- Bb Mean < Median>Mode
- Cc Mean < Median<Mode
- Dd Mean = Median=Mode
- Ee Mean > Median=Mode
