Understanding Histograms and Data Representation

The price range of pens

The number of pens sold

The total revenue from pen sales

The average price of pens

Only the upper limit is included

Only the lower limit is included

Neither limit is included

Both limits are included

Bar graphs represent quantities on both axes

Histograms use continuous intervals

Histograms do not use scales

Bar graphs use continuous intervals

Choosing a scale for the x-axis

Drawing the x and y axes

Labeling the bars

Calculating the frequency

1 cm equals 10 pens

1 cm equals 2 pens

1 cm equals 5 pens

1 cm equals 1 pen

10 pens

25 pens

15 pens

20 pens

2 centimeters

3 centimeters

5 centimeters

4 centimeters

Discrete data

Continuous class intervals

Qualitative data

Categorical data

This will be explained in another video

The histogram becomes a bar graph

The data cannot be plotted

The intervals need to be adjusted

It is the midpoint of the interval

It is never included

It is always included

It becomes the lower limit of the next interval
