Tests displaying numerical data in statistical plots on number line: dot plots (dots stacked at values), histograms (bars for binned intervals), box plots (five-number summary with box and whiskers). Dot plot: number line with values, stack dots vertically above each value (if data has three 7's, three dots stacked at 7 on number line, shows frequency by stack height and distribution by position). Histogram: bin data into intervals (60-69, 70-79, etc.), draw bars with heights=frequencies (7 students scored 70-79: bar height 7), bars touch (continuous data), shows shape (symmetric, skewed) and frequency distribution. Box plot: five-number summary (min, Q1, median, Q3, max), draw box from Q1 to Q3 (IQR=middle 50%), line at median inside box, whiskers extend to min and max (shows spread and center, identifies outliers if beyond whiskers). For the sorted data 11,12,12,13,14,15,16, the correct box plot uses min 11, Q1 12 (median of lower half 11,12,12), median 13, Q3 15 (median of upper half 14,15,16), max 16, with box from 12 to 15, median line at 13, and whiskers to 11 and 16. Errors include wrong Q3 like 14 or boxing from min to max. Creating a box plot: order data, find five-number summary, draw box and whiskers; this shows the data is fairly symmetric around the median.

Tests displaying numerical data in statistical plots on number line: dot plots (dots stacked at values), histograms (bars for binned intervals), box plots (five-number summary with box and whiskers). Dot plot: number line with values, stack dots vertically above each value (if data has three 7's, three dots stacked at 7 on number line, shows frequency by stack height and distribution by position); Histogram: bin data into intervals (60-69, 70-79, etc.), draw bars with heights=frequencies (7 students scored 70-79: bar height 7), bars touch (continuous data), shows shape (symmetric, skewed) and frequency distribution; Box plot: five-number summary (min, Q1, median, Q3, max), draw box from Q1 to Q3 (IQR=middle 50%), line at median inside box, whiskers extend to min and max (shows spread and center, identifies outliers if beyond whiskers). For example, data 5,6,6,7,7,7,8,8,10 displayed as dot plot: number line 5-10, stack dots (one at 5, two at 6, three at 7, two at 8, one at 10, shows mode at 7 with most dots); or histogram: scores binned 60-69(3), 70-79(7), 80-89(5), 90-100(2), bars touching at heights 3,7,5,2; or box plot: data 20,25,30,35,40,50,60 gives min=20, Q1=27.5, median=35, Q3=45, max=60, plot shows box from 27.5 to 45, line at 35, whiskers to 20 and 60. The correct histogram for reading minutes is choice A, with bars touching and heights 1, 4, 6, 3 for bins 0–9, 10–19, 20–29, 30–39. Common errors include separating bars with gaps (choice B), swapping heights like 4 and 6 (choice C), or incorrect frequencies such as starting with 2 (choice D). Creating dot plot: (1) draw number line with appropriate scale (min to max of data), (2) mark each data value with dot above number line, (3) stack dots if repeated values (three 7's→three dots stacked at 7); Histogram: (1) bin data (group into intervals: 0-9, 10-19, etc.), (2) count frequency per bin, (3) draw bars touching with heights=frequencies. Box plot: (1) find five-number summary (min, Q1, median, Q3, max from ordered data), (2) draw box from Q1 to Q3, (3) line at median, (4) whiskers to min/max; Interpreting: dot plot shows exact values and mode (most dots), histogram shows shape and frequency distribution, box plot shows spread (IQR, range) and center (median); Mistakes: dot plot stacking horizontal, histogram gaps, box plot box wrong extent, scale issues, frequency errors.

Tests displaying numerical data in statistical plots on number line: dot plots (dots stacked at values), histograms (bars for binned intervals), box plots (five-number summary with box and whiskers). Dot plot: number line with values, stack dots vertically above each value (if data has three 7's, three dots stacked at 7 on number line, shows frequency by stack height and distribution by position); Histogram: bin data into intervals (60-69, 70-79, etc.), draw bars with heights=frequencies (7 students scored 70-79: bar height 7), bars touch (continuous data), shows shape (symmetric, skewed) and frequency distribution; Box plot: five-number summary (min, Q1, median, Q3, max), draw box from Q1 to Q3 (IQR=middle 50%), line at median inside box, whiskers extend to min and max (shows spread and center, identifies outliers if beyond whiskers). For example, data 5,6,6,7,7,7,8,8,10 displayed as dot plot: number line 5-10, stack dots (one at 5, two at 6, three at 7, two at 8, one at 10, shows mode at 7 with most dots); or histogram: scores binned 60-69(3), 70-79(7), 80-89(5), 90-100(2), bars touching at heights 3,7,5,2; or box plot: data 20,25,30,35,40,50,60 gives min=20, Q1=27.5, median=35, Q3=45, max=60, plot shows box from 27.5 to 45, line at 35, whiskers to 20 and 60. The correct box plot for the plant heights is choice A, with min 12, Q1=14.5, median 15.5, Q3=19, max 21, box from 14.5 to 19, median line at 15.5, and whiskers to 12 and 21. Common errors include incorrect quartiles and boxing from min to max (choice B), missing the median line (choice C), or wrong five-number summary values (choice D). Creating dot plot: (1) draw number line with appropriate scale (min to max of data), (2) mark each data value with dot above number line, (3) stack dots if repeated values (three 7's→three dots stacked at 7); Box plot: (1) find five-number summary (min, Q1, median, Q3, max from ordered data), (2) draw box from Q1 to Q3, (3) line at median, (4) whiskers to min/max. Interpreting: dot plot shows exact values and mode (most dots), histogram shows shape and frequency distribution, box plot shows spread (IQR, range) and center (median); Mistakes: dot plot stacking horizontal, histogram gaps, box plot box wrong extent, scale issues, frequency errors.

Box plot: five-number summary (min, Q1, median, Q3, max), draw box from Q1 to Q3 (IQR=middle 50%), line at median inside box, whiskers extend to min and max (shows spread and center, identifies outliers if beyond whiskers). For the data 1,2,2,3,3,3,4,5,5,6, the correct dot plot has counts 1→1 dot, 2→2 dots, 3→3 dots, 4→1 dot, 5→2 dots, 6→1 dot, stacked vertically. Errors include incorrect counts like swapping frequencies or placing dots horizontally instead of stacking. Creating a dot plot involves drawing a number line from min to max, placing a dot for each data point above its value, and stacking for repeats; this plot shows the mode at 3 with the tallest stack.

Box plot: five-number summary (min, Q1, median, Q3, max), draw box from Q1 to Q3 (IQR=middle 50%), line at median inside box, whiskers extend to min and max (shows spread and center, identifies outliers if beyond whiskers). For showing exact temperatures like 62 (twice), 64 (thrice) and their frequencies in a small dataset, the best choice is a dot plot, which displays each value with stacked dots for repeats. Other plots like histograms bin values losing exactness, box plots summarize without frequencies, and pie charts suit categorical data not numerical. Choosing and creating: select dot plot for precise value display; mistakes include using histograms for small exact data sets.

The best plot type to show each exact value and frequency is dot plot, which is option B. An error would be choosing histogram which bins data and hides exact values, or box plot which summarizes without frequencies. Creating dot plot: (1) draw number line with appropriate scale (min to max of data), (2) mark each data value with dot above number line, (3) stack dots if repeated values (three 7's→three dots stacked at 7). Interpreting: dot plot shows exact values and mode (most dots). Mistakes: choosing inappropriate plot type for small data sets where exact values are needed.

The correct dot plot for apples sold is choice A, with dots at 18(2), 19(1), 20(3), 21(1), 22(2), 23(0), 24(1) stacked vertically from 18 to 24. Common errors include wrong frequencies like 18(1) and 24(2) (choice B), skipping values on the scale like 23 (choice C), or incorrect counts such as 23(1) and 24(0) (choice D). Creating dot plot: (1) draw number line with appropriate scale (min to max of data), (2) mark each data value with dot above number line, (3) stack dots if repeated values (three 7's→three dots stacked at 7).

Box plot: five-number summary (min, Q1, median, Q3, max), draw box from Q1 to Q3 (IQR=middle 50%), line at median inside box, whiskers extend to min and max (shows spread and center, identifies outliers if beyond whiskers). For example, histogram: scores binned 60-69(3), 70-79(7), 80-89(5), 90-100(2), bars touching at heights 3,7,5,2. The correct histogram has touching bars with heights 2,5,4,1 over 60–69, 70–79, 80–89, 90–99, which is option A. An error would be bars with gaps as in option C, or using categories instead of intervals as in D. Histogram: (1) bin data (group into intervals: 60-69, etc.), (2) count frequency per bin, (3) draw bars touching with heights=frequencies. Interpreting: histogram shows shape and frequency distribution. Mistakes: gaps between bars, wrong heights like 4 instead of 5 for 70-79, or non-interval labels.

The correct dot plot has dot counts 18→2, 19→1, 20→3, 21→2, 22→3, 23→1 stacked vertically, which is option A. An error would be incomplete scale missing 23 as in D, or wrong counts like 20→2 instead of 3 in B. Creating dot plot: (1) draw number line with appropriate scale (min to max of data), (2) mark each data value with dot above number line, (3) stack dots if repeated values (three 22's→three dots stacked at 22). Interpreting: dot plot shows exact values and mode (most dots, here at 20 and 22). Mistakes: frequency count wrong, scale doesn't include all data, or not stacking vertically.
